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?

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
