I am having issues with SORBS as welll.

It has blocked my mail domain as it thinks I have a Dynamic IP

sindows.net forward resolves to but
does not reverse resolve to sindows.net; you have no reverse dns.

That alone is enough to get your mail blocked nowadays.

I'll second that. We've taken to 4XX (tempfail) on unknown client during the day when our mail loads are high. this has greatly reduced the amount of SPAM we handle. I can't leave it on all day because too many clueless net/mail admins sending legitimate mail (20-30% i estimate) also don't have valid rDNS.
