The SMTP/LMTP client already implements some of the "flags" features
of the pipe(8) daemon:
Documented in smtp(8), lmtp(8):
flags=DORX (optional)
Documented in pipe(8):
flags=BDFORXhqu.> (optional)
Optional message processing flags. By default, a message is
copied unchanged.
One of these flags enables case-folding for the envelope recipient
address localpart:
u Fold the command-line $original_recipient and $recipient
address localpart (text to the left of the right-most @
character) to lower case. This is recommended for deliv-
ery via UUCP.
For user interface consistency, we should add this flag to the
SMTP/LMTP client, even if the underlying implementation won't share
code with the pipe daemon.
