as long as you set max_rcpt=1 on this transport. This defeats Cyrus'
single-instance storage of messages to multiple local recipients, so I
only use this transport for local parts that have a suffix attached;
all others go through a standard Cyrus transport that uses anonymous
posting, since the INBOX folders will always allow that.
IMHO, the patch to the LMTP transport is not required (and actually, I
think the LMTP transport itself should go away, since the SMTP
transport in LMTP mode can do everything it does, with a little more
overhead).
