[Dovecot] mail_max_userip_connections exceeded.

[Simon Brereton]

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 at 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
