Not that it helps at all but: It's the recipient's mail server that's broken not yours. Why anyone would relinquish control of their mail system to a third party who makes arbitrary decisions about what is and what is not a legitimate source of email is beyond me. There are tools that actually identify spam without relying on third parties that can totally break you mail system at any time.

Good afternoon, The reason why ORDB/SORBS is blacklisting the IP class 70.50.x.x is that it as been identified as a dynamic pool in the reverse lookup. In that range their are dynamic and static The reverse DNS that Bell provides on these IP's does meet SORBS requirements and our department were informed that the DNS will not be modified. Unfortunately, this type of static IP service does not include modification of the reverse DNS. There are other type of services available that will allow your company to change the PTR, it is called Business Internet Dedicated ADSL (15gig) with static IP. With the service you currently have, you can in theory host a website and a mail server but some ISPs will refuse mail if the reverse DNS indicates a dynamic IP address range. If your goal is to host your own mail server that will allow all mail to be accepted, we suggest to go with the Business Internet Dedicated ADSL (15gig) with static IP service. You contact the sales department at 1-888-676-7777. Otherwise you can setup your mail server to use Bell's (smtp.bellnet.ca). Be sure to contact us if you have any further concerns or comments. Regards, Chris Robinson Bell Internet Management Services - Service Investigations abuse@xxxxxxxxxxxxxx ---snip--- So I guess the smtp.bellnet.ca ends up in the smart host of the SMTP server?

FYI, his IP only fails that test, no other, although Andrew should request a valid PTR with the actual server name, but then again he knows what he is do so...
