Disabling chroot doesn't fix the issue, it just worked around it.

Oh….

Aparently your chroot is not configured correctly, likely using debian based system, and your resolv.conf in the chroot is not updated correctly.

Using FreeBSD here, not Debian.

I have no chroot configured for Postfix at all. The wiki page does not clearly mention this requirement.

Quoting Dan Langille dan@langille.org:

I wanted to mention I updated the Postfix and Dovecot SASL wiki entry yesterday.

http://wiki2.dovecot.org/HowTo/PostfixAndDovecotSASL

The entry:

submission inet n - - - - smtpd

was incorrect. It should be:

submission inet n - n - - smtpd

By specifying n for chroot, it ensures that DNS lookups can occur. Otherwise, if you are using reject_unknown_recipient_domain the following error will occur: Recipient address rejected: Domain not found

Hope that helps. — Dan Langille http://langille.org/
