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;
}
