Hi
I'm using Dovecot version 1:1.2.15-7 installed on Debian Squeeze via apt-get..
I have this error in the logs. /var/log/mail.log.1:2490:Jan 19 12:02:55 mail dovecot: imap-login: Maximum number of connections from user+IP exceeded (mail_max_userip_connections): user=user@example.com, method=PLAIN, rip=127.0.0.1, secured
I never changed this from the default 10. When I googled this error there was a thread on this list from May 2011 that indicated one would need one connection per user per subscribed folder. However, I know that user doesn't have 10 folders, let alone 10 subscribed folders! I can increase, it but it's not going to scale well. And there are people on this list with many 1000x users than I have - so how do they deal with that?
127.0.0.1 is obviously webmail (IMP5).
So, how/why am I seeing this, and should I be concerned?
Simon
