نپذیرفتن ایمیل های پوچ

Tired of seeing your mail queue fill up with bounce messages to non-existant spammer email addresses? By default, if an email comes into your server addressed to an invalid recipient, Exim will accept the message from the delivering agent, and then generate a return email to them explaining that the address is invalid. With this little tweak, you can make exim tell the delivering agent that that address is invalid at the time the message is being delivered, meaning no more spam returns cluttering up your queue! Can I get an Amen!? Read on!

Section A:
accept domains = +local_domains
accept domains = +relay_domains
accept hosts = +relay_hosts
accept condition = ${perl{checkrelayhost}{$sender_host_address}}

Between

accept domains = +local_domains

and

accept domains = +relay_domains

add the following:

endpass
message = unknown user
verify = recipient

Make sure each line lines up. You might need to add two spaces before each line. The final section will look like this:

accept domains = +local_domains
endpass
message = unknown user
verify = recipient
accept domains = +relay_domains
accept hosts = +relay_hosts
accept condition = ${perl{checkrelayhost}{$sender_host_address}}

Scroll all the way to the bottom and click on Save.

That's it! Welcome to much smaller mail queues!
