Fetch сервер сообщает об ошибке err maildrop already locked

E одного из пользователей с утра начало выскакивать сообщение об ошибке — «Mdaemon — Ошибка ERR maildrop already locked».

Как оказалось 2 или больше клиентов не могут в одно и то же время обращаться к одному почтовому ящику. Только по очереди. Поэтому кто первый подключился, того и тапочки. Второму юзеру сервер отвечает именно этой ошибкой.

Как оказалось юзер сам еще жал кнопку принять/отправить почту раз несколько подряд. И ему выскакивало окно ввода пароля для ящика. Перезагрузка машины и внушение в мозг юзеру решил все проблемы.

• Hello Mohammad,

  This typically happens if more than one client is trying to connect to an account at the same time using POP. Is this affecting a specific account or multiple accounts? Do you have the option to use IMAP or are you required to use POP in your environment?

I have multiple email addresses on a Win2K server running ALTN’s mdeamon. Works Great!

I have used other programs in the past that have not resulted in the server responding with:

«Sending of password did not succeed. Mail server … responded: maildrop already locked.»

I have looked in Thunderbirds tools/options and have seen no setting for this type of error. I have also looked at the mail server to see if there was anything I could do to resolve this error.

As I previously said, I have not gotten this error while using two other email programs.

Would anyone know of a way I could get around this error?

Thanks.

This is an ALTN error due to a lock file that is created that allows only one Pop3 session open at a time. They suggest that the user not check their email repeatedly so quickly. I may be able to get around this if I could tell Thunderbird in what order to check the mail. I do not see any options for that.

If you select the account and then click Get mail, it will only get mail for that account. Also, what do you have set in Tools>Account Settings>*each account*>Server Settings for Check for mail every xxx minutes and for Check for new message on startup? You may need to do this all manually with your server rather than use the automatic settings. You could also try staggering the minutes setting.

Hi!
It seems TB doesn’t recognize if logon was successful or there was another problem on the server not related to the logon and it asks enter usernam/password.
When two email clients are trying access the same mail box at the same time (or when TB was ungratefully terminated during it’s new email check and it didn’t disconnect from the server), the server (in my case it’s MDaemon) will wait NN minutes to automatically terminate the the first connected session (if connection is idle). During that time no other email client is permitted to receive/send emails using that account. It will return

ERR maildrop already locked

When TB receives such error, it getting confused and asks to enter username/password for the account, it might fill the password field for you (from password manager) however it doesn’t check the checkbox «Use password manager to store password», so if you simply hit enter without ticking that checkbox it will accept the entry and will remove the logon information from the «password manager»!
The next time it tries connect to email server it will ask for enter username/password again. — this is so annoying!!!!!
And there is no option to suppress password prompt? Give a notification that doesn’t require user interaction such as warning at status bar, or something more visible, something that would not halt the entire PB process from doing it’s other things while waiting for the user.

As of now, is there a way to «teach» TB to ignore certain error messages returned by the email server?

Thank you.

P.S.
Here is server’s log when the error occur:
