Re: Problem with Majordomo bonzo

Daniel,

I did telnet on my majordomo server having sendmail and sent the email
as suggested by you and it was ok. No error received.
Please let me know where should I check now.

Appreciate your generous help.

This seems to be much more specific than just "outside your domain".
Let us "trace back" the email that comes into majordomo.

1.  majordomo is called out by sendmail via the aliases file(s)
	majordomo.cf and/or your listname.conf files can reject mail 2.
If an alias does not exist, the passwd file is checked 3.  sendmail (or
compatible) MTA listens for mail on port 25, 465, or 587
	sendmail.cf, access, generics, and virtuser tables can all
reject
	incoming mail just like a firewall.
4.  local users typically have different rule sets than non-local users
5.  DMZ implies firewall,

If you log onto the application server in your DMZ and telnet to port 25
of your majordomo server, do you get a sendmail banner message?
	quit is the command to exit from the connection If you give
"EHLO " followed by your appserver hostname, do you get a list of
250-responses?  Or do you get some other response?
If you give "mail from: <[email protected]>" do you get a
sender ok reponse?
If you then say "rcpt to: <[email protected]>" what happens?

If all of the above is successful, we can start to look at majordomo and
the list configuration files as suspect.  This of course assumes there
are no other mail filters between sendmail and majordomo.
