I am pretty sure I have postfix to avoid acting like a relay for unauthenticated connections. But this maybe something I have messed up. This has been happening only since I upgraded to 11.2 (I was at 9.x). I also just recently switch from sendmail to postfix as well. I can provide my postfix config on request if needed. Pointers to other mail-lists are welcomed. I decided to start here before jumping on the postfix mailing list. Thanks in advance, Patrick
