John, would it be possible for you to tell me the steps to check this
problem?

I would look in your sendmail configuration at the place this message is
generated as it looks like it is a sendmail config problem. Perhaps you
have restricted delivery to only those in the system alias file and not
the majordomo list alias file.

I did one more thing. As I said earlier that whenever our application
server is sending emails to majordomo it is bouncing back with error:
"<<< 553 5.3.0 <capplication @
appserver .
hostname>... You do not have
permission send to this address
550 5.1.1 listname @
your .
domain .
.
.
User unknown"
When I did the telnet on port 25 on my majordomo server as per given
steps by you and tried to send email, it was successful.
But when I tried to send email via our gateway server with telnet (which
is in DMZ and the bridgehead for sending emails inside our domain),
after entering rcpt to:listname @
your .
domain, I got the same error "You
do not have permissions send to this address".
I hope it'll help to narrow down my issue.
Thanks,
Vikas

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: <application @
appserver .
hostname>" do you get a
sender ok reponse?
If you then say "rcpt to: <listname @
your .
domain>" 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.
