[Dovecot] per-user limit?

[Peter Hessler]

I am seeing a problem where users are limited to 6 imap logins total.
One of my users has a bunch of phones and computers, and wants them all
on at the same time.

I'm looking through my configuration, and I cannot see a limit on how
many times a single user can connect.  He is connecting from different
IPs.

Any ideas?  My logs show the following error when they attempt to auth
for a 7th time:

dovecot: imap-login: Disconnected (no auth attempts): rip=111.yy.zz.xx, lip=81.209.183.113, TLS
