I'm not sure whether this is related or not, however...
Squirrelmail will not accept usern...@domain.com plus password for
login - it will only accept username plus password:
ERROR:
ERROR: Connection dropped by IMAP server.
Query: LOGOUT
Connecting with a mail client, either format (usern...@domain.com or
username) works.
Obviously, I'd like to fix this as well but it's less urgent than the
lack of ability to send email from Squirrelmail. I'm just not sure
whether one may perhaps have something to do with the other...

This toaster has been up and running for a few weeks now and, to the
best of my knowledge (I almost never use the webmail interface),
outgoing mail from Squirrelmail WAS working fine up until yesterday.
Yesterday, staff started seeing the following when trying to send an
email from Squirrelmail:
ERROR:
Message not sent. Server replied:
Service not available, closing channel
421 out of memory (#4.3.0)
I've already tried increasing the softlimit - it didn't help. I've
also tried increasing storage (from 8 to 16GB) and RAM (from 2 to 4GB)
on the VM - also didn't help (didn't really expect it to but it was
worth a shot).
Sending messages works fine from a mail client, so the problem appears
to be specific to Squirrelmail and/or port 587. Testing via telnet
from the webserver confirms that port 587 is the culprit:
[root@qmail tcprules.d]# telnet localhost 587
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

Suggestions??
