First - use dummy MX records. Real mail retries. Botnet and must spammers don't. It's easier for them to try to spam someone else than to fight your filter. MX config is as follows:dummy - 10 real - 20 real-backups - 30 dummy - 40 dummy - 50 dummy - 60
Currently I have mail.mydomain.com as 10. Can I just change that to 20 and add mail5.mydomain.com as 10 but not have an IP associated with mail5.mydomain.com or will that cause trouble? Matt
