My host provides an smtp server for sending mail. I want to setup sendmail to relay all emails to the hosts smtp server. How do you do that?

2I can tell you the term you want is "smart host" but I don't know how to set it up in sendmail.– DerfKMay 13, 2011 at 1:50

It's a little difficult to answer your question without more context on your email environment. That being said, the general steps would be:
1) Edit /etc/mail/sendmail.cf
2) Search for "DS"
You'll find a section that looks like this:
# "Smart" relay host (may be null)
DSrelay:[]
3) Put the downstream mail server IP in the square brackets.
4) Save changes. Bounce sendmail service.
Again, I have to reiterate that this is a general guideline. Your mileage may vary.

Well normally I just point any program that needs to send email to the hosts smtp server but I didn't see an option for it in Anope and I read that it sends mail only by using sendmail.– WillMay 13, 2011 at 3:43

1One thing to note though is that since this is a Debian system, the sendmail binary might actually be part of exim and not sendmail (the sendmail.org mailer).– adamoMay 16, 2011 at 15:07
