Viktor had already helped me fix the "unknown" issue. Here is an example Received header for a domain with a dedicated IP of 74.63.3.132 :) Received: from www.alwaysbuywholesale.com (www.alwaysbuywholesale.com [74.63.3.132]) by vps.velvetpixel.net The mismatch issue I mentioned I am still trying to solve is: server vps.velvetpixel.net 74.63.2.190 telnet 74.63.2.190 smtp Trying 74.63.2.190... Connected to vps.velvetpixel.net. Escape character is '^]'. 220 vps.velvetpixel.net ESMTP Postfix <-- this is s match!!! virtual host with dedicated IP alwaysbuywholesale.com 74.63.3.132 telnet 74.63.3.132 smtp Trying 74.63.3.132... Connected to alwaysbuywholesale.com. Escape character is '^]'. 220 vps.velvetpixel.net ESMTP Postfix <--This is not a match :( How do I change the SMTP banner for just the vhost dedicated IP 74.63.3.132 to 220 www.alwaysbuywholesale.com ESMTP Postfix and still keep the correct banner of 220 vps.velvetpixel.net ESMTP Postfix for 74.63.2.190? I can update my PTR for 74.63.3.132 so it is www.alwaysbuywholesale.com instead of alwaysbuywholesale.com but how do I change the banner for that dedicated IP so it then matches www.alwaysbuywholesale.com?
