I've been exploring, both on my mail-server-to-be, and on the Dovecot mailing list, just why it is that the Dovecot deliver program is leaving the domain string empty when formulating the mail location path. The answer I'm getting now on that list is that it is a Postfix problem and that I should ask on THIS list?
Does that make any sense to anyone here? Just wondering if anyone here has done Postfix+Dovecot and made it work ... and better yet, documented how to make the two talk to each other. What I have so far has (in one incarnation) gotten mail successfully delivered. But the path as defined in Dovecot's mail_location = configuration which had %d in there to fill in the recipient domain name as part of the path, got an empty string there, even though the domain name was passed along by Postfix. I'm not sure what role Postfix would have in that. But maybe a sanity check is in order (and this is making me start to go insane). I've attached outputs from "dovecot -n", "postconf -n", and "postfinger", with redactions to obscure domain names and IP addresses.
