As spammers have already guessed, the companies that we do business for, ie. hosting their site, are whitelisted by domain. So, what I would really want is something that can be implemented on our end, rather than on the companies end because we have over 200 clients. This SPF, Sender Policy Framework... how would I use that? Please forgive my lack of knowledge in this area. I appreciate any help you can offer. _____________________________________________ tmda-users mailing list ([EMAIL PROTECTED]) http://tmda.net/lists/listinfo/tmda-users
