How do I send mail to my google apps mail server from the webserver with the same name (using sendmail)?

Question

Mail for my domain is handled by google apps service, all required DNS MX records entered correctly. Also I have webserver that handles HTTP requests for the domain. And I can't send mail from that server to my mail domain, sendmail ignores MX records and always trying to deliver all messages for my domain locally.

Looks like it consider domain name as local if it resolves to local ip address.

This is a cut from the logs:

Feb  7 18:03:03 vds sendmail[4100]: n17I33c2004100: [email protected]... User unknown
Feb  7 18:03:03 vds sendmail[4100]: n17I33c2004100: [email protected], delay=00:00:00, mailer=local, pri=0, dsn=5.1.1, stat=User unknown
Feb  7 18:03:03 vds sendmail[4100]: n17I33c2004100: from=root, size=36, class=0, nrcpts=1, msgid=<[email protected]>, relay=root@localhost

Answer 1

Ditch sendmail and get postfix. Sendmail is difficult to configure correctly, and difficult to keep secure. Postfix is easy on both counts. I have no experience with them, but I'm told that qmail and exim are equally good.

Answer 2

Well. Found a solution for my case.

Just add the following line to your source .mc-file and recreate sendmail.cf

define(`confDONT_PROBE_INTERFACES', `true')

Answer 3

It solved mine too. I was having the same problem. That is, my sendmail was delivering messages locally instead of delivering them to the Google Apps mail account.

Thanks.

Thank God for your comment, Rubens, "my sendmail was delivering messages locally instead of delivering them to the Google Apps mail account"! That's where all the missing emails are that my programs have been trying to send to various employees. Unfortunately I don't understand the solution "define(confDONT_PROBE_INTERFACES', true')". Is someone willing to talk to me further on this?

Answer 5

While I'm looking for the solution for the same issue on my server, there is a work around for you: go to your google app email box, to settings/accounts, then create a new account to pull the emails from, as mail server specify IP of your own server and also give it username and password that was working for your previous mailing solution (before google apps).

That way you'll have google sign into your local mail server and pick up all the 'lost' emails, each 10 or so minutes.
