ISTR those are (generally) created on MS 'lookout' o/e (if even legit at
all..) AND that MS has 'fixed' that a while back, so it should be a
gradually vanishing issue.
Otherwise, the sending MTA often adds a message-ID for such (as Exim can
do..)
If NEITHER - simply reject them at smtp time.
Ex:
# DATA_7: IF NOT proper headers THEN [warn | deny].
#
# warn
deny
message = X-Broken-Mailer: Headers violate RFC2822 standard.
log_message = D7 missing message-id, date, or subject headers
condition = ${if or {{!def:h_Message-ID:} {!def:h_Date:} \
{!def:h_Subject:}} {true}{false}}
That places the onus where it belongs - on the sending MUA / MTA to fix
*their* (not *your*) problem.
CAVEAT - a 'deny' may be too draconian for some folks...
