I have a couple postoffices that should only receive email from a specific SMTP server. Is it possible to configure the system to only allow mail from that server to be accepted for a couple specific postoffices? This is a spam situation and the SMTP server in question is their filter.
Thanks!
Receive mail from only one source?
Re: Receive mail from only one source?
This post is very interesting.
In our case the users (400+) are exposed to a lot of spam but we manage to filter most of it.
In most domains we have the mx10 our anti spam server and the mx20 Mailenable. In some domains I have tried to leave only mx10(spamfilter) and reduce some spam attacks.
I would also like to know if we can configure that mailenable that accepts incoming mail only from the IP of the antispam server.
I have seen a post mentioning to activate the option SMTP>Advanced SMTP> "Inbound Authentication" and verify that the IP of our spamfilter is already authorized in SMTP> Relay>Privileged IP's.

Forgive my bad English, I used the translator. I hope I have explained myself well

SMTP settings > inbound tab. Change to Denied access Except for those listed below and add your spam filter IP to the list.

Re: Receive mail from only one source?
Unfortunately changing the the "denied access except" effects the whole server. Many postoffices don't have a spam-catch server so they have to be able to get mail from everywhere.
