Exim 4.54, FreeBSD 4.11. Clamav, SA, dovecot, PostgreSQL)
Our acl, from one 'donated' here a few year ago, reads:
# DATA_8: IF NOT ours AND NOT proper other headers THEN deny.
#
deny
message = Message does not conform to RFC2822 standard.
log_message = missing required header lines
!hosts = +relay_from_hosts
!senders = : postmaster@*
condition = ${if !eq {$acl_m0}{accept}{true}}
condition = ${if or {{!def:h_Message-ID:}\
{!def:h_Date:}\
{!def:h_Subject:}} {true}{false}}
We are rejecting everything from (only?) demon.co.uk's mail.demon.net
servers.
Analysis of messages provided by the correspondent through less-strict
channels indicate that demon, who are using Exim 4.42, are apparently
stripping headers, as the 'message-id' header is absent.
grepping the most recent 27,513 message to this list (all that I have on
my PowerBook) does not turn up anything
on the matter of message-id. (or demon.co.uk // demon.net)
Are we the 'Lone Ranger in checking for this header?
... or are 'demon' odd-man-out in omitting the RFC-compliant 'message-id'?
