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?
