If the hosting company is some-hoster.com then (adjusting file pathing appropriately) it might look like so: Forward: (/var/named/some-hoster.com) mail.some-hoster.com IN A 1.2.3.4 PTR: (/var/named/3.2.1.0-arpa) 4 IN PTR mail.some-hoster.com. The hosting company should send/receive from their mail server no matter how many accounts they have. If they need more than one mail server, then use 1.2.3.5 and call it mail2 or something. The server should also spit out something like this when you telnet to them: [EMAIL PROTECTED] ewheeler]$ telnet mail.some-hoster.com 25 Trying 1.2.3.4... Connected to mail.some-hoster.com (1.2.3.4). Escape character is '^]'. 220 mail.some-hoster.com ESMTP mail relay. ^]q By doing this, the rdns, fdns and 220 banner all match and senders should be happy :) -Eric Eric Wheeler Vice President National Security Concepts, Inc.
