How To Stop All SMTP Traffic to a Domain?

carlosinfl · 04-22-2008, 07:48 AM

I want to disable all incoming and outgoing SMTP traffic to a specific domain on my Postfix email server. Right now I do NOT want users to be able to send to a specific domain nor do I want my email server to accept messages from that domain. Has anyone done this and can assist me in setting this parameter up on my Postfix server?

add a couple lines to /etc/mail/access (assuming thats the location on your server)

Code:

badbadbad.com                     ERROR:5.0.0:550 We dont like you
To:badbadbad.com		  REJECT

ooh shoot! i didn't see "postfix" till after i submitted. I hate ADD somtimes

So this will not work for Postfix?

Or you can simply just remove the MX records for that domain, that's like rejecting the mail at the post office instead of at your own mailbox (server).
