[TriLUG] Need a Stupid Sendmail trick

[Dave Sorenson]

They allow outbound 25 from their network through their SMTP server only. So
by setting up smarthost in sendmail I can bounce it through
mail.bellsouth.net. When I'm outside the Bellsouth network
mail.bellsouth.net will not allow me to relay out bound (As it should),
that's why I want to be able to relay through my server which would be
inside their network. So in short, if I can get Sendmail to accept on a non
blocked incoming port I can relay through Bellsouth.

If they are blocking outbound SMTP, how are you sending emails from your
local email client out to anyone??  (Sorry I can't help with sendmail, I use
postfix)
