When fetching mail from a mailbox after the
12th messages mailbee complaints that there is
a wrong user/password and disconnects from the
server.

What actually happens is that mailbee makes to
many connections to the IMAP server, causing
the disconnects. This did not happen before
updating to the latest version.

This is what the imap server shows:

Nov 21 11:26:06 mail1 dovecot: imap-login:
Maximum number of connections from user+IP
exceeded: user=<####@###.##>, method=PLAIN,
rip=82.94.255.251,
Nov 21 11:26:06 mail1 dovecot: auth(default):
new auth connection: pid=41340

How can I prevent this from happening inside
mailbee?

How many connections will mailbee try to make?
If that would be mentioned I could also change
some settings on the imap server.

(I commented out the email address in the
logging rule)

Any update to this issue?

It seems we have a few users who complain of a similar situation when trying to retrieve a large number of emails from a remote email box. It will bring in a few messages, then an error occurs saying "Can't connect to POP3 server check POP3 server settings".

If we keep checking for mail eventually the box empties down and everything is fine again, but if a lot of messages are there initially it is a real pain to get them downloaded.

In the case above, the issue was caused by memory limit. We recommended the customer to increase MEMORYLIMIT value in common/inc_constants.php and memory_limit setting in PHP configuration file (the first setting has higher priority in most cases) and that helped.

Please try to follow the suggestion and if it doesn't help, provide us with the log file.

Best regards,
Andrew
