Mailbox already locked

Support General Configuration

Hello.
I use axigen 10.3.3.
I faced a strange error.
when a one user try to connect to his mailbox through POP3s, axigen returns message “mailbox already locked”.

mail POP3:00001C88: [...:995] connection accepted from [...:50145]
mail POP3:00001C88: >> +OK AXIGEN POP3 server on mail.my.domain ready postmaster@my.domain
mail POP3:00001C88: << CAPA

mail POP3:00001C88: >> -ERR mailbox already locked
mail POP3:00001C88: << QUIT
mail POP3:00001C88: >> +OK POP3 server closing connection

do you have any idea about this problem?

Hi Mohammad,

Thank you for your message.

Please know that the POP3 account automatically locks for only one session if there are two different POP3 sessions connected to the same account.

Please note that regardless of the maximum number of POP3 sessions configured, the POP3 standard RFC1939 requires an exclusive access lock to be set on the mailbox once one POP3 session is authenticated.

You can disable the mailbox lock action for POP3 using the below CLI commands:

<#> config server
<server#> set pop3ExclusiveLock no
<server#> commit
<#> save config

Best regards,
Razvan
