[olug] Cox and port 25

[David Walker]

Do either ssh port forwarding as I describe separately or configure an smtp 
server at work that is not on port 25.

Personally I also approve of the measure.  Every virus these days seems to 
spread via e-mail and many of them try connect impersonate other users by 
sending mail through the impersonated user's mail server.  This measure 
disables those viruses and gives Cox a method to throttle spam.  It certainly 
has it's downsides, like what if their server is down and you still need to 
send mail? what if their server gets placed on blacklists and your mail gets 
rejected? etc.  I get around those problems with ssh port forwarding (or I 
would if I still lived in Omaha and had Cox.  I am in Lincoln with Earthlink 
cable now)
