[TriLUG] email (imap) setup question

[Heath Holcomb]

Port 113 is identd, pop3 is port 110. Some IRC servers force clients to 
have identd running, but I'm not sure why IMAP would need it. You don't 
say what IMAP implentation you're using, but I use courier IMAP and it 
doesn't seem to require identd. I don't know about UW IMAP, but I would 
imagine you can also configure it to not do this check.
