Debian – Setup sendmail to relay to another smtp

debiandebian-lennyemailsendmail

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?

Best Answer

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.
