I have an application I'm testing which requires a frequent login/logout
of the mail system. My DSL provider's mail system keeps crapping out on
me...probably thinks I'm spamming or running a business. I have a
single UNIX machine setup behind a static IP DSL modem/firewall. I've
forwarded port 25 from my modem to my machine. I'm trying to understand
what I need to do to get emails to/from my machine and the Internet.
Can anyone point me in the right direction?

Thanks,
