But requiring that an IP have a reverse dns, would this be based on the MX record for the sending domain? Then how can an IP have multiple reverse DNS? Also I've been wating almost two months for the "dns guy" where I colo my servers to get back to you. If anyone really checked for reverse dns I'd be in trouble because I cant even get someone to setup the reverse dns, my ip block is only 24 addresses that have been reassigned to me so I CANT setup the reverse dns anyways.

How does it react when the DNS server in charge of that PTR record is down? It seems as if it refuses the mail with a permanent error instead of trying to resolve a few more times and then returning a temporary error. And I'll ask yet again; isn't the error response "Server access forbidden by your IP" a bit cryptic? One of the reasons for implementing such a check is to try to get other mail servers to fix such problems, but you need to give the user a little more to go on, so they can relay an educated complaint to their system admins... If the error message can't be changed, would it be, or is it already, possible to have macros (like @@FROM in MAILPROC.TAB) in CustomSMTPMessage so I can pass the error response and IP address of the offending SMTP server in a querystring to my error description page, allowing me to help the user a bit more in telling them how to get their problem fixed w/o taking a call? Like "Please open http://www.myserver.com/errors.pl?smtpip=@@SMTPIP&error=@@ERROR to get more information about this error" Well, for now SMTP-RDNSCheck stays off. Too much legitimate mail is refused, and way too many support calls asking what "Server access forbidden by your IP" means... most think they are on a ban list.
