First I'd like to thank all the developers and contributors to dovecot. I've been using it for many years, and deeply appreciate your fine work. :)
dovecot --version 2.2.22 (fe789d2)
I have a working installation with postfix and dovecot, and I want to add sieve to it, so I am trying to configure postfix to use lmtp instead of 'virtual' for its delivery service. However it is ignoring that request, and for every message I get "status=sent (delivered to maildir)" and it shows up in my Inbox.
On my mail host I have 1 normal user, let's say the username is 'myuser'. I have postfix configured to accept mail for several different domains, and each domain has a lot of different mail usernames (I use this for mailing lists and such). I use the virtual_maps feature of postfix, and have a map file that looks like this:
abuse@dougbarton.us myuser hostmaster@dougbarton.us myuser dougb@dougbarton.us myuser ...
All of this works great, and mail for all the different usernames and domains gets delivered into my one real user's Maildir, and I can see the mail with my IMAP clients.
I've configured sieve in dovecot, and I can see the socket for lmtp in /var/spool/postfix/private/. I can also see the managesieve port in netstat, and I can use a sieve client to connect to it and edit scripts, etc.
So according to all the tutorials I've read my next step is this in postfix' main.cf:
virtual_transport = lmtp:unix:private/dovecot-lmtp
which I did, and postfix restarts with no errors. But, it seems to avoid lmtp altogether, and as I mentioned above it delivers straight to my Maildir Inbox every time.
I do have a sieve file, and the ~/dovecot.sieve symlink exists. I created a very simple filter:
require ["fileinto", "imap4flags"];
if header :contains "Subject" "test" { fileinto "Junk"; }
which my sieve client says is correct syntax. Still no joy. :-/
Any thoughts or suggestions are welcome. (And sorry this is so long, but based on my extensive searches it seems my configuration is a bit unique, so I explained it in some length.)
