sendmail user authentication

[Dave van Nierop]

I am running sendmail 8.9.3 and trying to send emails to a smart host (DS macro) that is running CommuniGate Pro 4.1 software. When I use /usr/lib/sendmail -v user@domain and enter a sample message, the session fails with "575 root@domain.com sender requires authentication"
/etc/mail/sendmail.cf is not using user authentication option.

However, if I telnet directly to the CommuniGate smtp port and enter the ehlo, mail from:, rcpt to:, data, etc. it succeeds. Conclusion is that I am bypassing the hp-ux 11.11 sendmail.

PS: I tried running sendmail in debug mode using flags "-v -d8.99 -d 38.99" as well but can't find anything to pin this down.

Anybody have any ideas?

Are you using domain masquerading? If not, do you get different results with it configured (DM=default domain)?

DM is set, but exact same symptom.

Try with these debug options:

-d0.4 -d1 -d6 -d8.1 -d10 -d11 -d20.1 -d40.4 -d42.2

hopefully there will be something in there that shows you at what point in the process the 575 is being generated, which in turn will point to what piece is broken/not configured right.
