Topic: Restrict sending to certain domains

Hi,

I have installed iRedmail 4.0 in RHEL 5. I just wanted to know is there a way to restrict sending emails to certain domains
for eg:
I just wanted to restrict internal users sending emails "abc.com", they should be dropped.

Thanks,
Sandun

Re: Restrict sending to certain domains

You can use postfix smtp restriction classes and header check.
See official postfix document:
