Hi, has anyone seen this issue before as I have not.

I'm a long time dovecot user and I don't see anything in the config that should cause this.

The mail.log gets hit a lot of times with this same log message:

dovecot: imap-login: Maximum number of connections from user+IP exceeded (mail_max_userip_connections)

I have noted that it is more evident when I try to mass delete many messages.

Any ideas of how to diagnose this issue?

The dovecot -n follows:
