Sorry I wasn't clear enough. My "handshke to set things up" was meant to keep out spammers. The idea was that the final receiving MTA would know that it was expecting forwarded mail for user@domain from a set of IP addresses. I was picturing something like: user goes to final MTA and says I want you to accept forwarded mail for me from example.com then he goes to example.com and says "please forward my mail to m...@final.com" example.com would then contact final.com and say "OK if I forward me's mail to you?" If yes, then example.com says "Here are the IP addresses I use for forwarding...." -- These are my opinions. I hate spam. _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
