Hi Rafael, I see no problem in your smtp daemon kickin mail back with "Unresolved Sender Domain". sender must resolve properly, sender must also be the MX of domain. Anything else, and most likely one of the three things happened: -1- Vintage computer got infected with one of them worms, and is spattering e-mail far and wide. -2- [EMAIL PROTECTED] -3- i forgot this one :-) the mail could be legit. but the sender has a dns misconfiguration that prevents them from being resolved properly. Cheers Szemir
