[olug] Cox and port 25

[Nathan Rotschafer (OLUG)]

Now I could be in the minority of people who actually do care about what 
others think about my email and thus I run postfix and a spam scanner and 
virus scanner on all incoming AND OUTGOING mail.  This helps cut down on a 
lot of problems I have seen.  Additionally I only allow authenticated SMTP 
(in this case a pop [or imap] before smtp solutions for postfix).  With all 
of these measures I have stayed off of every black list I have checked and 
very rarely do I get spam delivered to me or virus (which of course doesn't 
really matter since I use Linux but hey).  I have personally not had this 
port 25 issue yet, but if I do you better believe I will complain up a storm 
till they change the policy.
