[Dovecot] Sieve is not getting the propper RCPT from the LMTP daemon
Hi!
Since the setup I use is a bit strange let's go for it first:
* The system uses postfix as MTA and dovecot as LDA after alias
translation by local via LMTP
* The dovecot version is 2.2.5 and the pigeonhole version is 0.4.1
* The SMTP server at gentoo.org is configured to send me a backup of my
emails to klondike+gentoo (at) xiscosoft.es using sendmail
* The email is received by the server and then (hopefully filtered).
* The email comes with two Delivered-To: headers, the first one has the
correct address, the second one has the gentoo address.
The interesting part of the filter is this:
if envelope :detail "to" "gentoo"
{
addflag "\\Seen";
fileinto "gentoo";
stop;
}
But this doesn't seem to work, I enable debugging with the following lines:
require "vnd.dovecot.debug";
require "envelope";
require "variables";
if envelope :matches "to" "*" { debug_log "envelope to `${1}'"; }
if envelope :matches "from" "*" { debug_log "envelope from `${1}'"; }
The relevant lines for the test e-mail I sent are these:
sieve: info: started log at Dec 24 13:37:23.
main script: line 9: info: DEBUG: envelope to `klondike (at) gentoo.org'.
main script: line 10: info: DEBUG: envelope from `klondike (at) gentoo.org'.
info: msgid=<52B97FF7.6050109@gentoo.org>: stored mail into mailbox 'INBOX'.
The thing is that the to envelope should be instead klondike+gentoo (at)
xiscosoft.es as show by the lmtp logs:
Dec 24 13:37:23 localhost dovecot: lmtp(26249): Connect from local

- The system uses postfix as MTA and dovecot as LDA after alias
- The dovecot version is 2.2.5 and the pigeonhole version is 0.4.1 Tried also today with 2.2.6 and 0.4.2 with the same results
BTW Timo, thanks for the verbose error messages, LMTP refused to work until postmaster_address wasn't set (despite the config still states it will go back to a default) and the logs clearly pointed that :-)

A similar issue was mentioned and solved a little later on the mailing list, so that is why I forgot about this one. That involved Sendmail though:
http://www.dovecot.org/list/dovecot/2014-January/094385.html
So, did you manage to solve this yourself?
If not:
- What is your config: dovecot -n
- Do you have an example message?
- Can you capture the LMTP protocol exchange between Postfix and Dovecot somehow?
Regards,
Stephan.

If you read further down that thread, you'll see that both Miquel van Smoorenburg and Steffen Kaiser pointed out that this solution only works in the case where there is one and only one recipient. So it's not a general solution.
Because of that, I am using dovecot LDA instead of LMTP until I can write a custom sendmail ruleset to pass +detail to LMTP. Here's my sendmail LDA configuration ($h contains the detail part of the ID):
FEATURE(local_procmail', /usr/local/libexec/dovecot/dovecot-lda', `dovecot-lda -a $u+$h -d $u')

That is true, if you want to fetch the envelope recipient from "Recieved" headers.

LMTP in sendmail has the problem, that you need to accept "user+detail" as local recipient, in order to be passed to the local mailer. I did this with a socket map, because I use one anyway. Also, if getpwnam() is not working, you loose the .forward feature. Therefore I patched a Dovecot mailbox backend, similiar to the already existing LDAP mailbox backend, into sendmail.
