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/
