+## LMTP
 once Postfix 3.5 is on stable, we can use the X-Original-To header with LMTP as well. Simply add the "flags=O" argument to the `lmtp` line in `master.cf`, and change `local_transport` in `main.cf` to be `lmtp:unix:private/dovecot-lmtp` and also add the parameter `lmtp_recipient_limit = 1` to `main.cf` as well. Also, feel free to delete the `15-lda` config file from the git for dovecot
 
 alternatively, could potentially use the `envelope-dsn` extension of Sieve if it is added to Pigeonhole
