This is trivial to do with MIMEDefang.
Just use the filter_helo() function:
sub filter_helo($$$$$$) {
my ($hostip, $hostname, $helo, $hostport, $serverip, $serverport) = @_;
md_syslog('debug', "helo: $hostname ($hostip:$hostport) said \"helo
$helo\””);
return ('CONTINUE', "OK");
}
and make sure you’re running mimedefang with the -H option (or with
MX_HELO_CHECK=yes for RH Linux).
