Ошибка 552 message size exceeds the limit

Users sending messages with attachments to recipients hosted in Exchange servers can end up receiving bounce mails due these attachments.

Our Support Engineers support hundreds of Exchange servers for web hosts, web designers and other online businesses.

In these servers, we’ve seen huge attachments or unsupported attachments formats causing email error 552.

The error message seen by the senders in the bounce mail in cases of huge attachment size limit would be error 552 – ‘5.3.4 Message size exceeds fixed maximum message size’.

If the bounce happens due to the content of the attachment, the error message would be similar to error 552 – ‘5.7.0 Our system detected an illegal attachment on your message.’

What is email error 552 ‘5.3.4 Message size exceeds fixed maximum message size’

Every mail server has custom settings for the size of mails users can send and receive through it. These limits can either be global or individual-account specific or both.

To limit bandwidth usage, this email size limit is often restricted to a few MBs in most servers. If the email size exceeds that limit, it will be rejected by the mail server.

Error 552 ‘5.3.4 Message size exceeds fixed maximum message size’ is an email error commonly seen in bounce messages that generate from recipients using Exchange mail server.

In an Exchange server, there are mainly 4 settings for message size limitations:

a. Global value for the mail server
b. Receive and Send Connectors setting
c. SMTP Virtual Server setting
d. Individual user mailbox restriction

If the message size in the email exceeds any of these limits that are allowed for a particular email user account, it will be rejected with this error 552 message.

To resolve a valid email bouncing with error 552, these attachment limits have to be increased or adjusted appropriately.

But before we get into the detailed steps on how to increase these limits to accept valid user mails with attachments, we’ll see how these message size limits are to be calculated.

How to determine the email message size limits?

In Exchange mail servers, content conversion happens for mails. Exchange server converts an internet/MIME message to MAPI/Exchange format, and vice versa for transmission.

After this content conversion process, the message size generally increases by about 30%. As a result, a message of 9 MB may fail to deliver to a server with size limit 10 MB.

Also, the precedence of the message size limits has to be noted before changing the settings. The maximum allowable message size for a server should be set as the organizational limit.

If the message is sent to or received to the server from a user on the Internet, this organizational limit will be applied to that mail.

But for internal users who send mail to each other after successful authentication, the user mailbox limit takes precedence over all other size restrictions.

So, for a server to accept messages from the internet with size around 15 MB, all the message limits should be set at 20 MB, considering the content conversion size.

How to fix error 552 ‘5.3.4 Message size exceeds fixed maximum message size’ in Exchange server

To accept mails of large sizes from valid senders, the message size settings have to be increased in the server. Here’s how to do it for each limit:

1. How to increase global message size settings

The global default message size limit for Exchange Servers 2007 to 2010 is 10 MB. To change this value, the steps are:

1. Open the Exchange Management Console.
2. Click on Organization Configuration -> Hub Transport.
3. Click on Global Settings -> Transport Settings.
4. On the Properties -> General tab, set the maximum send and receive size limits.

This is the organizational setting and would be applicable to all mails sent and received from that server over the internet.

2. How to change message size limits for Receive connector

Receive connectors are the gateways through which all inbound messages are received to a mail server.

The maximum message size limit for a mail that can be received on a receive connector can be set by:

1. Open the Exchange Management Console
2. Click on Server Configuration -> Hub Transport
3. Select a Hub Transport server
4. Click on Receive Connectors
5. Choose the receive connector and Click on Properties
6. Click on the General tab and set the maximum message size

Setting a limit on receive connector can further limit the message size based on the sender’s IP address or type.

3. How to change message size limits for Send connector

Send connectors are configured to change the email sending behavior in server. To change the maximum message size limit on send connectors, do these steps:

1. Open the Exchange Management Console
2. Click on Organization Configuration -> Hub Transport
3. Click on Send Connectors
4. Choose a send connector and Click on Properties
5. Click on the General tab and set the maximum message size.

This limit is used to limit the size of outgoing mails from a server.

4. How to increase message size settings for individual mail accounts

The individual mailbox settings can be changed from Exchange Administration Center (EAC). Here’s how to do it:

1. In the EAC, go to Recipients > Mailboxes.

2. Select the mailbox that you want to change the message size limits for, and then click Edit.

3. On the mailbox Properties page, click Mailbox Features.

4. Under Message Size Restrictions, change the following message size limits:

5. Sent messages - sets the maximum size of message that can be sent by the user. The value has to be set in KBs.

6. Received messages  - give the maximum size of messages that can be received by this user account in KBs.

7. Click OK and Save the changes.

User mailbox settings are usually set to limit or override the default global size of email messages sent between users within the same server.

All these email settings should be verified one by one to ensure that mails to the recipients are delivered successfully without bouncing with the error 552 ‘5.3.4 Message size exceeds fixed maximum message size’.

Почтовый агент Postfix позволяет задавать различные ограничения, таймауты и лимиты. В данной инструкции мы рассмотрим примеры, как это сделать. Используемые значения подойдут для средне статистического сервера, однако, в каждой среде необходимо наблюдение и приведение параметром к оптимальному виду.

Редактирование конфигурационного файла
Размер почтового ящика
Размер отправляемого сообщения
Количество сообщений
Очередь сообщений
Таймаут на отправку
Сообщения об ошибках
Ошибка message size exceeds fixed limit
Работа с конфигом postfix

Редактирование конфигурационного файла Postfix

Изменения делаем в конфигурационном файле:

vi /etc/postfix/main.cf

* для FreeBSD путь будет /usr/local/etc/postfix/main.cf.

После редактирования не забываем перечитывать изменения командой:

systemctl reload postfix

* для FreeBSD или старых систем на базе Linux вводим service postfix restart.

1. Размер почтового ящика

Для установки квоты на почтовые ящики редактируем следующее:

mailbox_size_limit = 209715200
virtual_mailbox_limit = 209715200

* значение указывается в байтах. В данном примере установлены квоты для почтовых ящиков и виртуальных почтовых ящиков в 200 мб. Для удобства, воспользуйтесь конвертером мегабайт.

Чтобы снять ограничения, можно выставить значения в 0:

mailbox_size_limit = 0
virtual_mailbox_limit = 0

2. Размер отправляемого сообщения

Открываем конфигурационный файл, находим и правим следующее (если строки нет, создаем):

message_size_limit = 73400320

*  в данном примере установлено ограничение на размер письма в 70 мб.

Необходимо, чтобы данный размер не превышал размер почтового ящика (mailbox_size_limit и virtual_mailbox_limit, которые по умолчанию имеют значения 51200000 или 50 мб), в противном случае, в логе мы увидим ошибку fatal: main.cf configuration error: mailbox_size_limit is smaller than message_size_limit.

Для этого можно либо задать значения равные (или больше) message_size_limit:

message_size_limit = 73400320
mailbox_size_limit = 73400320
virtual_mailbox_limit = 73400320

… либо отключить ограничения:

message_size_limit = 73400320
mailbox_size_limit = 0
virtual_mailbox_limit = 0

3. Количество сообщений и одновременных подключений

В конфигурационном файле добавляем такие строки:

anvil_rate_time_unit = 60s
smtpd_client_message_rate_limit = 200
smtpd_client_recipient_rate_limit = 60
smtpd_client_connection_count_limit = 20
smtpd_client_connection_rate_limit = 40

* в данном примере мы установили следующие ограничения на количество отправляемых писем: 

• anvil_rate_time_unit — параметр расчетного времени. Именно от него будут вести отчет другие значения. По умолчанию также равен 60s.
• smtpd_client_message_rate_limit — сколько клиенту можно отправлять сообщений за anvil_rate_time_unit. По умолчанию 0, то есть, ограничений нет.
• smtpd_client_recipient_rate_limit — максимальное количество получателей за anvil_rate_time_unit. По умолчанию 0, то есть, ограничений нет.
• smtpd_client_connection_count_limit — количество одновременно разрешенных подключений для клиента. По умолчанию 50.
• smtpd_client_connection_rate_limit — максимальное количество коннектов, разрешенных для клиента за anvil_rate_time_unit. По умолчанию 0, то есть, ограничений нет.

4. Очередь сообщений

queue_run_delay = 5m
minimal_backoff_time = 10m
maximal_backoff_time = 15m
maximal_queue_lifetime = 1d

* где queue_run_delay задает время, как часто сообщения из очереди будут отправляться повторно; minimal_backoff_time устанавливает время, на которое будет отложена отправка сообщений, которые не были отправлены по причине временных неисправностей (например, принимающий сервер не отвечает или просит повторить запрос позже), но не позднее maximal_backoff_time; параметр maximal_queue_lifetime установит, через какой период перестать делать попытки при отправке сообщения и вернуть его отправителю с ошибкой.

5. Таймаут на отправку сообщений

smtp_data_done_timeout = 600s
smtp_data_init_timeout = 120s
smtp_data_xfer_timeout = 180s

* где smtp_data_done_timeout — ограничение времени для отправки сообщения; smtp_data_init_timeout — ограничение времени для отправки команды SMTP DATA и для получения ответа удаленного SMTP-сервера; smtp_data_xfer_timeout — ограничение времени для отправки содержимого сообщений.

6. Отправка сообщений об ошибках (4xx or 5xx)

smtpd_error_sleep_time = 3s
smtpd_soft_error_limit = 5
smtpd_hard_error_limit = 10

* где:

• smtpd_error_sleep_time — задержка перед отправкой сообщения об ошибке (4xx or 5xx). По умолчанию 1s.
• smtpd_soft_error_limit — количество ошибок, которые должны быть сделаны, прежде чем наш сервер начнет замедлять ответы. По умолчанию 10.
• smtpd_hard_error_limit — максимальное количество ошибок, которые может сделать удаленный сервер SMTP. После с ним будет разорвана сессия. По умолчанию 20.

552 5.3.4 message size exceeds fixed limit

Если сталкиваемся с сообщением «552 5.3.4 message size exceeds fixed limit» (переводится как «Размер сообщения превышает установленные ограничения»), значит отправляемое письмо не вписывается в установленные лимиты. Чтобы исправить ситуацию, уменьшаем размер сообщения или редактируем лимиты (пункты 1 и 2).

То есть, размер message_size_limit не должен превышать mailbox_size_limit и virtual_mailbox_limit.

Работа с конфигом postfix

Неколько полезных консольных команд по работе с конфигурацией.

1. Посмотреть значение параметра по умолчанию:

postconf -d <Параметр>

Например:

postconf -d mailbox_size_limit

2. Посмотреть текущее значение параметра:

postconf -n <Параметр>

Например:

postconf -n message_size_limit

3. Изменить значение:

postconf -e «<Параметр = значение>»

Например: 

postconf -e «virtual_mailbox_limit = 0»

Customers sending messages with associations with recipients worked within Exchange servers can end up getting ricochet sends due to these associations. Our Support Engineers support many Exchange servers for website-trained professionals and other electronic associations. In these servers, “552 Size Limit Exceeded Gmail, the Best Strategy to Fix It!”, we’ve seen colossal associations or unsupported association plans causing email error 552.

The screw-up message seen by the senders in the ricochet mail in cases of monstrous association size cutoff would be error 552 – ‘5.3.4 Message size outperforms fixed most outrageous message size’.

If the skip happens due to the substance of the association, “552 Size Limit Exceeded Gmail, the Best Strategy to Fix It!”, the bungle message would resemble error 552 – ‘5.7.0 Our system distinguished an unlawful association on your message.’

What is email error 552 ‘5.3.4 Message size outperforms fixed most noteworthy message size’

Each mail server has custom settings for the size of sends customers can send and traverse it. These cutoff focuses can either be worldwide or individual-account express or both. To limit move speed use, this email size limit is consistently bound to several MBs in numerous servers.

In case the email size outperforms that limit, “552 Size Limit Exceeded Gmail, the Best Strategy to Fix It!”, will be excused by the mail server. Mix-up 552 ‘5.3.4 Message size outperforms fixed most outrageous message size’ is an email error typically found in ricochet messages that produce by recipients using the Exchange mail server.

In an Exchange server, there are mostly 4 settings for message size imperatives:

1. Overall motivator for the mail server
2. Get and Send Connectors setting
3. SMTP Virtual Server setting
4. Individual customer letterbox constraint

If the message size in the email outperforms any of these limits that are viewed as a particular email customer account, it will be excused with this misstep of 552 messages.

To decide a generous email ricocheting with error 552, “552 Size Limit Exceeded Gmail, the Best Strategy to Fix It!”, these association limits should be extended or changed appropriately.

Nevertheless, before we get into the separated strides on the most ideal way of growing these cutoff focuses to recognize generous customer sends with associations, we’ll see how these message size limits are not set in stone.

How do choose the email message size limits?

In Exchange mail servers, content change happens for sends. Exchange server changes over a web/MIME message to MAPI/Exchange arrangement, just as the opposite way around for transmission.

After this substance change process, the message size overall additions by around 30%. In this manner, “552 Size Limit Exceeded Gmail, the Best Strategy to Fix It!”, a message of 9 MB may disregard to pass on to a server with a size limit of 10 MB.

Furthermore, the need for the message size limits should be noted preceding changing the settings. The most outrageous acceptable message size for a waiter should be drawn as the various leveled line.

If the message is delivered off or gotten to the server from a customer on the Internet, this definitive limit will be applied to that mail. “552 Size Limit Exceeded Gmail, the Best Strategy to Fix It!”, In any case, for inside customers who send letters to each other after viable approval, the customer post box limit dominates any leftover size restrictions.

Thusly, for a server to recognize messages from the web with a size of around 15 MB, all quite far should be set at 20 MB, considering the substance change size.

Guidelines to fix error 552 ‘5.3.4 Message size outperforms fixed most outrageous message size’ in Exchange server

To recognize sends of tremendous sizes from considerable senders, the message size settings should be extended in the server. “552 Size Limit Exceeded Gmail, the Best Strategy to Fix It!”, Here is the way of doing it for every cutoff:

1. Bit by bit directions to augment overall message size settings

The overall default message size limit for Exchange Servers 2007 to 2010 is 10 MB. To change this value, the means are:

1. Open the Exchange Management Console.
2. Snap on Organization Configuration – > Hub Transport.
3. Snap on Global Settings – > Transport Settings.
4. On the Properties – > General tab set the most limit to send and get size limits.

This is the definitive setting and would be material to all sends sent and got from that server over the web.

2. The best technique to change message size limits for Receiving connector

Get connectors are the entryways through which all inbound messages are gotten to a mail server. “552 Size Limit Exceeded Gmail, the Best Strategy to Fix It!”, The most outrageous message size limit for a mail that can be gotten on a get connector can be set by:

1. Open the Exchange Management Console
2. Snap-on Server Configuration – > Hub Transport
3. Select a Hub Transport server
4. Snap-on Receive Connectors
5. Pick the get connector and Click on Properties
6. Snap on the General tab and set the best message size

Putting down a limit on getting a connector can moreover confine the message size subject to the sender’s IP address or type.

3. The best technique to change message size limits for the Send connector

Send connectors are intended to change the email sending conduct in the server. To change the most outrageous message size limit on send connectors, “552 Size Limit Exceeded Gmail, the Best Strategy to Fix It!”, do these methods:

1. Open the Exchange Management Console
2. Snap-on Organization Configuration – > Hub Transport
3. Snap-on Send Connectors
4. Pick a send connector and Click on Properties
5. Snap on the General tab and set the most outrageous message size.

This limit is used to confine the size of dynamic sends from a server.

4. The best strategy to grow message size settings for individual mail accounts

The particular letterbox settings can be changed from Exchange Administration Center (EAC). Here are how to do it:

1. In the EAC, go to Recipients > Mailboxes.
2. Select the letter drop that you wanted to change the message size limits for, and a while later snap Edit.
3. On the letter drop Properties page, click Mailbox Features.
4. Under Message Size Restrictions, change the going with message size limits:
5. Sent messages – sets the most outrageous size of the message that can be sent by the customer. The value should be set in KBs.
6. Gotten messages – give the most outrageous size of messages that can be gotten by this customer account in KBs.
7. Snap OK and Save the changes.

Customer letterbox settings are typically attracted to line or supplant the default overall size of email messages sent between customers inside a comparable server.

“552 Size Limit Exceeded Gmail, the Best Strategy to Fix It!”, All of these email settings should be affirm independently to ensure that ships off the recipients are passed on adequately without ricocheting with the misstep 552 '5.3.4 Message size outperforms fixed most noteworthy message size'.

Termination Result

552 email error due to message size cutoff can show up in various designs too, “552 Size Limit Exceeded Gmail, the Best Strategy to Fix It!”, for instance,

• #552 5.2.3 Message outperforms close by size limit.
• ##552 5.3.4 Message size outperforms fixed limit
• 552 message size outperforms the most outrageous message size
• _#552 size limit outperformed

The message size and association size for messages should be define to reasonable boundaries, “552 Size Limit Exceed Gmail, the Best Strategy to Fix It!”, for productive mail transport to happen. However, it’s not reasonable to assemble the message size pointlessly, as it will end up over-troubling the server.

Error Codes and Solutions for Bounce

Before proceeding with the error code and fixes. To be explicit, 5xx means hard bounce, and 4xx means soft bounce. In the world of SMTP, hard bounces are emails that can never be deliver. While soft bounces are emails that can be deliver after some time has pass.

1: Error 441 4.4.1

when sending an email Network is overload! An email sent to the recipient’s email provider failed to respond to the sender’s request, resulting in this error.

Solution: The sender’s email server will retry a few times before passing on more information to the sender’s server. If the sender is unable to deliver, the message is a lineup.

2: 452 4.2.2 Error

Mailbox Is Full Because the recipient’s inbox is full, an email was not deliver to the recipient’s MX server.

Solution: These emails can be resent, and they automatically send a note to the sender requesting that the recipient check or empty their inbox so that new emails can be deliver.

3: Network Connection Timed Out 421 4.4.2

The link between the sender and the receiver was lost before the emails were deliver, which cause the error.

Solution: Because these responses are instantaneous when network connections are lost, you can always attempt sending it again later.

4: 5.0.0 Unknown Issue Error

Message Not Delivered Reason: The email was not deliver, but the server has no idea why.

Solution: This error indicates that there may be issues with the email address, such as spelling errors or missing letters (symbols). As a result, using universal email regex, these emails can be filter away. You can try again after correcting the email addresses. Also, add the proper email address to your contact list. If the issue persists, contact your user via an alternative channel. Such as phone, message, or chat, to confirm the right email address.

5: 5.2.0 Undefined or other mailbox status Error

The email was not delivere to the recipient’s mailbox due to an unknown problem.

Solution: Because this is undefined or unknown to the email system, the solution is the same as the previous issue. It is preferable to check the email address syntax for any invalid characters or spelling errors. If the problem persists, consider contacting the user via alternative channels.

6: 554 5.2.2 Mailbox is overflowing

The recipient’s inbox is full and he or she is unable to receive additional emails.

Solution: Contact your recipient via various means and request that they delete any undesire emails so that space can be made available for future emails.

8: Error 552 5.2.3 – Message Is Too Long Reason

The email sent exceeded the maximum length allowed by the recipient’s email system setup, preventing delivery.

Solution: Make sure the email body only contains the necessary information and attachments. If at all possible, split the emails into two or more. so that the emails are deliver successfully If the problem persists after reducing the email, get assistance from your email service provider.

9: Transaction 5.5.4 failed.

Error Reason: This error is a component of 5.5.1 and 5.5.2 in which the sender’s server used a command to send an email that was not recognize by the recipient’s email server.

Solution: Resend the message to see if the problem is a one-time occurrence. If the same thing happens again. Check the username and password for your SMTP account. If the problem persists, contact your ESP for assistance.

10: 5.5.5 – The protocol version is incorrect.

Error The reason for this is that the sender’s and receiver’s email programs are incompatible, preventing an email from being deliver.

Conclusion

Other than changing quite far settings, and procedures, for instance, email tension can moreover be use in unequivocal cases. Furthermore, “552 Size Limit Exceed Gmail, the Best Strategy to Fix It!”, straight-away making server setting changes isn’t recommend as it would screw with its commonplace working.

Email error investigating incorporates taking a gander at the server logs, checking the sway message, perceiving the bungle creating a server, and cross-truly investigating the server settings. In case you’d like to acknowledge how to get your mail server and hinder email ricochet goofs, “552 Size Limit Exceeded Gmail, the Best Strategy to Fix It!”, we’d be happy to speak with you.

i’m trying to troubleshoot an issue where my users send large files and i want to increase the file size possible to get to the exchange mailbox but i’m not having success.  In a test internally from one exchange user to another i am able to send these
set of jpg files totalling 19mb.  But, when i send from the internet to the same user i get a failure.  Below are the details of the failure.  From my gmail accont to my exchange account.  Any advice on where to check or change settings? 
Further troubleshooting steps?

Also…i’m running Exchange 2010 and not 2013…the web page did not allow me to choose 2010 for some reason…
