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.
Right. Miquel van Smoorenburg pointed that out too earlier in this thread.
Do you serialize messages per recipient?
Yes, to mitigate this issue, I plan to enforce one recipient per LMTP
session with: define(LOCAL_MAILER_MAXMSGS', 1'). This will result in
adding "m=1" to the local mailer definition.
But I'd really rather have +detail passed via LMTP.
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')dnlof my mc-file effects it.
Now this is a really useful data point! I have exactly the same configuration on FreeBSD running sendmail v8.14.7:
FEATURE(local_lmtp',[IPC]',`FILE /var/run/dovecot/lmtp')
Mlocal, P=[IPC], F=lsDFMAw5:/|@qPSXmnz9, S=EnvFromSMTP/HdrFromL, R=EnvToL/HdrToL, T=DNS/RFC822/SMTP, A=FILE /var/run/dovecot/lmtp
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.

I'm not using any aliases or virtuser table in my tests, yet my sendmail DOES NOT pass +detail to LMTP:

So I clearly have a sendmail problem. Maybe there's been a regression in sendmail since 8.14.4, or there's some other platform specific issue. This gives me something to go on; thanks a lot for your feedback!
