We are running
postfix with single domain (example.com) currently and we have appropriate
PTR record for that.
Now we want to add one more domain but i want to isolate that domain totally, Even i want to isolate
PTR record too. so we added new
public IP address in same server and added
PTR entry to
- example.com - 220.127.116.11
- abc.com - 18.104.22.168
How i am going to tell postfix run example.com on
22.214.171.124 ip address and abc.com on
so from outside if someone try to telnet on 25 port he get different appropriate domain for relevant IP.
$ telnet mail.example.com 25 Trying ::1... Connected to mail.example.com. Escape character is '^]'. 220 mail.example.com ESMTP Postfix
And for abc.com
$telnet mail.abc.com 25 Trying ::1... Connected to mail.abc.com. Escape character is '^]'. 220 mail.abc.com ESMTP Postfix
