Reverse DNS can be the same on both. For forward lookups that's not possible, and there isn't any way for your mail server to know which pipe it's going out to be able to change its hostname. Very few servers check that forward and reverse matches, most just check for existence of PTR or that PTR matches EHLO. I'd keep it on one WAN, but have PTR on the second so you can fail over. That'll suffice for nearly all mail servers. > Also, is there a way to force the server to always use either the ATT or > Covad link to send mail? > Yes, setup your rules on the interface with the mail server accordingly. --------------------------------------------------------------------- To unsubscribe, e-mail: support-unsubscr...@pfsense.com For additional commands, e-mail: support-h...@pfsense.com Commercial support available - https://portal.pfsense.org
