sendmail won't use relay
The Derfer
a relay doesn't do it. Yes, the "DS" field is set up in sendmail.cf,
sendmail daemon restarted a million times, etc etc.
Everything looks fine, it just doesn't work.
Why does it try to send the mail itself? Shouldn't even attempt
a DNS lookup. The mailhost (relay) can do that but here, the
client tries to do it itself for some reason. Please advise.
I try sending a test
to see if this is working and here's what I get:

First: what you want is usually called a "SMART_HOST", and is normally
programmed from sendmail.mc, then the "make" command is run in /etc/
mail to senerate the new sendmail.cf file. SMART_HOST does *not*
redirect email to local accounts, such as "root": there's another
setting needed for that whose name escapes me. Editing sendmail.cf
directly is asking for pain, and won't properly reload the sendmail
daemon. Secondly, what does /var/log/maillog say about this case? And
third, I find sendmail's configuration tools to be pretty painful, and
have switched by preference to "postfix" a long time ago: postfix also
handles milters a lot more gracefully, so you might just consider
ripping out sendmail and using postfix instead.
