I thought that you'd be running with only a single user testing it. If
you've 60 users logged in at the same time it's pretty difficult to
figure out what's hanging.

You could run another Dovecot instance in a different port and have that
one user use a different port. Then you'd be able to find the login
process more easily (e.g. netstat -lnp). Running another instance is
explained in http://wiki.dovecot.org/RunningDovecot
