I have the MX records for zaltin.com set to the Google Apps domains (aspmx.l.google.com etc.). If an email is sent to kerrick@zaltin.com from most places, it goes to my Google Apps account. However, on the zaltin.com server (Ubuntu 10.04 if it matters), sending via SMTP (postfix), if I send to kerrick@zaltin.com (via the Pony ruby gem if it matters), it simply routes to kerrick@localhost (showing up via the mail command) instead of going to my Google Apps account (where it should show up in my GApps Gmail inbox).

Can I make email sent via SMTP on my server, through my server, not go to my server but to Google Apps?

You either have an entry in /etc/hosts pointing zaltin.com to localhost, like this:   zaltin.com

In which case you need to remove this, or you've configured Postfix to treate zaltin.com as a local destination in /etc/postfix/main.cf like this:

mydestination = localhost, zaltin.com

In which case you need to remove this.

  • Ah, I believe it's the second one. If I remove that, can I still send email from zaltin.com via postfix?

  • @Kerrick Yup, that doesn't restrict what From addresses you can use. As an aside, you should however setup SPF records.

    Yay, editing it out of that line fixed it! And I'll look into SPF records, thank you.
