[TriLUG] Need a Stupid Sendmail trick

Since I'm already configured for authentication before relay, I've
re-configured sendmail to listen on 587. It seems to be working to solve the
immediate issue, but I will know for sure tomorrow when I can test from
outside the Bellsouth network. Like I said, this is only temporary till my
lease is up and I make other arrangements. Thanks for all the suggestions!

Well, I recommend you switch to postfix and set up TLS on port 465 (the
standard smtp over SSL submission port).  If that port is blocked you can
choose another.  Here are some notes I made on this setup a while back:

Hope this helps, please let me know if you have questions about the setup.

Don't be scared of switching to postfix -- it's easy.  You'll probably spend
less time learning postfix than you would trying to configure sendmail to
make this one change!
