Hello all,
I have a real head scratcher. When sending email directly thru exchange to a known bad address, say sadfxs...@yahoo.com, I receive a bounce back, as I should, stating an invalid address. When I send the same email thru the same exchange server, this time with a postfix smarthost, I never receive a bounce back. Here is the mail flow: Client---àExchange-àPostfix-àInternet. Postfix is only configured for outbound email, exchange answers inbound email. Any suggestions? I don't know where else to look. I suspect that I configured postfix to be non-compliant to an RFC, but not sure what is the offending configuration. Any help is greatly appreciated. Nick
