Hello,

Since the update to iRedMail 0.9.6 some users get locked out. In the dovecot.log this entry is appearing:

Feb 22 15:15:39 imap-login: Info: Disconnected (no auth attempts in 0 secs): user=<>, rip=*.*.*.*, lip=*.*.*.*, TLS: Disconnected, session=<yWOPIR9J6AAlGJmz>

Are their clients misconfigured? Or is it a problem of the client software (K-9)? And what could they change to stop the server locking them out?

Thanks in advance!
