Global Filter for Rejecting Emails

[Umang Parekh]

Hello,

I am looking to create a Global Filter which can do the following.
Block all incoming emails which have
FromEmail address not equal to the reply_to address.

so if any incoming email has fromemail [email protected] and replyto is set to [email protected] must be rejected.

If anyone knows how this can be achieved then please suggest.

seems cpanel interface global email filter is what you are referring to.
The following documents offer some examples on how to implement custom filter rules:

How to Customize the Exim System Filter File - cPanel Knowledge Base - cPanel Documentation
How to Configure Mail Filters - cPanel Knowledge Base - cPanel Documentation

Thank you for the prompt response but the links do not solve my problem.
What I am looking to do is not explained in the links.
I think we need to create a filter using if then else.
where the if part has from_email not equal to reply_to email then reject else proceed.

If someone can help on this would be great.

You mean like this:


The Filter has matched the following condition(s):
$header_from: is [email protected] and $reply_address: contains [email protected]
$reply_address: contains [email protected]
$header_from: is [email protected]
Return-path copied from sender

Save message to: /dev/null 0660

Problem is We are receiving spam emails from unknown senders. So we are looking for a global filter with wildcard entry such as.
when an incoming email hits the server our global filter will check if the incoming email has set from email and reply to address as the same.

From: [email protected]****.co.za [mailto:[email protected]****.co.za]
Sent: Thursday, February 9, 2017 12:38 PM
Subject: Re: Purchase Order

Here the from email is [email protected]****.co.za and while replying to this email a new email address comes upfront i.e [email protected]****.co.za
We are looking to block such incoming emails who have this criteria where sender email is different from the replyto email address.
