Blocking outgoing mail to certain domains

Asked by alexkink in CPanel, Email Software

Tags: cpanel, email, email filtering

Hello,

I'm in need of a solution whereby I need to block outgoing mail from reaching certain domains OR certain email addresses. Lets say one of these blacklisted addresses is bob@acme.com

When an email user sends the following message, bob@acme.com must not receive it:

To: john@abc.com, bob@acme.com
Bcc: sam@internet.com
Subject: Hello
Body: Hi guys

The rest of the addresses must be able to get the message.
The mail server that I'm using is a hosting account that runs CPanel. I have Spam Assassin and BoxTrapper at my disposal but they seem to be limited to incoming mail only.
E-mail client software is mostly MS Outlook, but if other email clients support this functionality I can switch too.
If the solution involves using a different server software, I'm open to that too.
