SCO OS 5.05a, 600a, 497c, mmdf
PPP 56K dialup connection, dynamic IP.
I have a mail server that has worked very well for months until my account's
ISP changed the authentication for the SMTP server to try to stop spammers.
My mmdf bad users and hosts is set to deliver mail to their server. When my
server attempts to deliver mail, it attaches fine, gets hello from SMTP and
error: "550 not local host hotmail.com, not a gateway, unknown address,
cannot deliver, returned. Problem address ending, no valid addresses" My
bad hosts and users have not changed, only their authentication.
The mail is returned. The ISP said, Go into Outlook Express, Accounts,
Outgoing Mail server and Check "My server requires authentication" He also
said, "I don't know anything about unix"
Will the people who do know something about Unix please give me a clue as to
how I might get around this problem? If I had a static IP he could allow me
in but since I am using a dialup PPP connection (from Tony Lawrence) we
cannot go this route. Any ideas appreciated.
