That is possible. We have a direct access webmail system in place.
I'll check there.

No. The environment in a current case was this:

2007-12-08 19:22:16.642824500 dovecot: Info: pop3-login: Login: user=<yyyyyyyy>, method=PLAIN, rip=134.147.64.5, lip=134.147.64.16

Please don't put any work in that, it was rather rare and seems to have
