Re: [AFMUG] Email blocked because of Client IP, not Server IP
Sounds like he is sending mail directly out to the Internet (perhaps using a local SMTP server) instead of using your SMTP server.

Re: [AFMUG] Email blocked because of Client IP, not Server IP
he should get his IP addressed. It may be that his provider doesnt have appropriate reverse DNS, baracuda looks, I remember when we had to do it, we had our records listed with something like dynamic, or client or something, theres a list of words that flag you. but, of course this only matters if the ISP can or will do anything about it. He may be able to delist himself temporarily. It may also be he is just listed because he was relaying spam To verify this is the issue he can send an email to the same address one from a client, one from webmail, if the webmail gets through, then it verifies thats the actual problem.

It makes it check all IP addresses in all the headers, not just the connecting server's IP. ~Seth
