Steve,
I ran in to this problem in 5.09. Basically, it is a problem with imail's
SMTP server that only allows one client to authenticate at a time, in our
case it was another mail server trying to authenticate with cram-md5. The
authentication of the invalid client would fail, and iMail will wait until
it recieves a disconnect message from the client. Unfortunately this never
comes, and since iMail authentication was tied up to this user, none of your
valid users could connect.
I do believe 6.06 has corrected this as we have not had this problem since
upgrading (I never found any official word from ipswitch though, since they
denied that this situation is a problem.), and I would suggest upgrading.
If you enable SMTP logging, you should see lines very loosely resembling:
(linues surrounded by *'s are my comments.)

Hopefully this was what you are after.
