[TriLUG] email (imap) setup question

[Henryk M. Kowalski]

According to my /etc/services 113 is auth...  (Unless I have a flaky 
install.)
Port 25 is open to allow incoming email, and that has worked fine all 
along but the email server itself wants access to 'auth' when I try to 
read my email...
