I have postfix as my SMTP gateway server.I have 3 email domains.
I want to use this server only for my outgoing mails. I dont want any incoming mails flowing through this server.
If i dont configure MX record pointing to these IPs there wont be any incoming mails , but my outgoing mails will be considered as SPAM by the recipient gateway servers since i dont have mx record configured.
Let me know how can i achieve my scenario.
