[NTLUG:Discuss] Sendmail Problem?

[Richard Humphrey]

Heres what I did and it seems to work. I set my machine hostname to
match my hostname from dydndns.org. I have been sending out emails for
months with nho problems. I dont use the smtp.myprovider.com entry
either.

One other option I discovered when I ran into the same thing with AOL
was to put
an entry into the /etc/mail/mailertable file (SuSE).  This way, only
mail
destined for aol.com would go through my ISP's mail server.

aol.com                 smtp:[mail.attbi.com]

This works great just as long as your ISP doesn't require authentication
for
outgoing mail like my current ISP does (Verizon DSL).  Still trying to
figure
out the authentication part.
