I am trying to use my own SMTP server, not my ISPs.  Not only that, but 
I AM trying to authenticate.  As I said in my previous post, I can send 
when dialing in to the 'net, but not when connecting from the ghetto 
network I'm on here.  Only SMTP traffic seems to be stopping/timing 
out.  I can receive mail just fine.
