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:
1) Add "lda_original_recipient_header = X-Original-To" to 15-lda.conf
2) 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.
