Hi all,

I’ve got postfix setup to use dovecot-lmtp for (virtual) user delivery, and things to users or aliases that Dovecot knows about now get delivered correctly. However, I’ve done something wrong with postfix and/or the LMTP configuration because upon RCPT TO, instead of forwarding the mail off to the configured smartest, somehow dovecot-lmtp is ending up in the mix. (Perhaps this is more a postfix question than a dovecot one, but, I’ll start here.)

Relevant postfix config:

Given both of those configurations, shouldn’t it see that gmail address and send it off to the relay host?
