dovecot - Sep 2011 - director ignoring director_mail_servers for lmtp connections

Hello,

Following Jan-Frode's advise I am trying this configuration:


{postfix} ---lmtp---> {director} ---lmtp---> {dovecot}

so I have two dovecot instances for director/proxy and lmtp delivery on ports
1024 and 24 respectively.

whilst for imap connections I can specify a pool of imap backend servers via
'director_mail_servers' it seems is not possible with lmtp.

how I can redirect incoming lmtp request to backend lmtp servers (and not just
one)? what I'm missing here?

Is this a loop maybe?  director_mail_servers should list all
your backend dovecot servers, space separated. Here's mine:

	director_mail_servers = 192.168.42.7 192.168.42.8 192.168.42.9 192.168.42.10
192.168.42.11 192.168.42.28 192.168.42.29

and director_servers should list all your director servers so that they
can share info on where to direct each user, like:

	director_servers = 192.168.42.15 192.168.42.17

Then, if this is configured correctly "doveadm director status" should
list your backend director_mail_servers:

$ sudo doveadm  director status 
mail server ip                           vhosts users
192.168.42.28                               100  5220
192.168.42.29                               100  4733
<snip>
$ sudo doveadm  director status janfrode at tanso.net
Current: 192.168.42.28 (expires 2011-09-13 08:46:42)

it works with imap connections, so I assumed it also would do it for lmtp.


Sep 13 09:04:03 imap1 dovecot: imap-login: proxy(user001): started proxying to

using only one director and backend would be fine for tests purposes (as it was
with imap and not loops were formed)

What I don't understand is why director insists in providing a proxy host
from passdb when all it needs to do is pick the ones in director_mail_servers ??


Sep 12 17:14:13 imap1 dovecot: lmtp(25682): Error: proxy: host not given

please could you post you lmtp configuration??

Hello,

it works!!


I was missing this line


"auth_socket_path = director-userdb"
