I found this[1] thread that describes the same problem with dovecot-LDA, but the solution (add X-Original-To: header) has no effect with LMTP.
My sendmail LMTP configuration: FEATURE(
local_lmtp',[IPC]',`FILE /var/run/dovecot/lmtp')Sendmail's address test indicates that sendmail is providing user+detail to LMTP (see below). Except for this problem, dovecot, LMTP, and sieve are all working perfectly. Is there something I'm missing, or is this a bug?
[1] http://dovecot.org/pipermail/dovecot/2012-July/136987.htm
It seems I was mistaken. By tracing the LMTP session between dovecot and sendmail I found that sendmail does _not_ include the +detail in RCPT TO:. I also determined that dovecot LMTP will in fact extract the +detail from a X-Original-To: header, but only if one defines lda_original_recipient_header.
So for the archives, to get sieve's "envelope :detail ..." working with sendmail and dovecot LMTP, do the following:
Add "lda_original_recipient_header = X-Original-To" to 15-lda.conf
Add the following rule to sendmail.mc to add a X-Original-To: header to every message:
LOCAL_CONFIG H?${u}?X-Original-To: $u
First: This won't work, if the message has two or more recipients, $u is empty then. Do you serialize messages per recipient?
Second: My Debian sendmail v8.14.4 does pass +detail to LMTP.
Mlocal, P=[IPC], F=lsDFMAw5:/|@qPSXnz9, S=EnvFromSMTP/HdrFromL, R=EnvToL/HdrToL, T=DNS/RFC822/SMTP, A=FILE /var/run/dovecot2.2/lmtp
looks like just:
FEATURE(local_lmtp',[IPC]',`FILE /var/run/dovecot2.2/lmtp')dnl
of my mc-file effects it.
The use of forwarding, aliases or virtuser table might strip the detail, you need to do explicitly preserve the +detail with those. Retry with a recipient without any rewriting and from the local host.
