Re: Postfix and Dovecot SASL - wiki update

Disabling chroot doesn't fix the issue, it just worked around it. Aparently your chroot is not configured correctly, likely using debian
based system, and your resolv.conf in the chroot is not updated
correctly.

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/
