[Mimedefang] Message-ID

[Joseph Brennan]

When a message comes in with no Message-ID header, and MD passes it to
SpamAssassin, what is in the Message-ID that SA sees? It doesn't seem
to be NOQUEUE, since SA does not score INVALID_MSGID.

I'm considering scoring with SA for no Message-ID plus other factors.

Nothing at all. There's no Message-ID header in the message that gets passed
to SpamAssassin.

Dianne.

Are you sure?

spam_assassin_mail() calls gen_msgid_header().

Ah... apparently I was wrong.

I think that's a bug. I'm going to delete that line.

So, back to where we started. What will be in that generated Message-ID?
Would my mail host's name, the one that received the message, be in it?

See mimedefang.pl:

sub gen_msgid_header {
my ($ss, $mm, $hh, $mday, $mon, $year, $wday, $yday, $isdst) =
localtime(time);

# Generate a "random" message ID that looks
# similiar to sendmail's for SpamAssassin comparing
# Received / MessageID QueueID
return sprintf("Message-ID: <%04d%02d%02d%02d%02d.%s\@%s>\n",
$year + 1900,
$mon + 1,
$mday,
$hh,
$mm,
($QueueID eq 'NOQUEUE' ? rand() : $QueueID),
get_host_name()
);
}

Yes:

sub get_host_name {
# Use cached value if we have it
return $PrivateMyHostName if defined($PrivateMyHostName);

# Otherwise execute "hostname"
$PrivateMyHostName = hostname;

$PrivateMyHostName = "localhost" unless defined($PrivateMyHostName);

# Now make it FQDN
my($fqdn) = gethostbyname($PrivateMyHostName);
$PrivateMyHostName = $fqdn if (defined $fqdn) and length($fqdn) >
length($PrivateMyHostName);

return $PrivateMyHostName;
}
