    I've done some searching, and I've found some decade-old threads that say the hooks no longer work.......... and there's apparently a related new feature: SpamAssassin Scan Email Forwarders

    But nothing I've found so far does what I want: I want to prevent anyone from creating a forwarder that goes to certain domains. Gmail for now ( and I know for sure); maybe,, and would be good ideas, too...

    What started this quest: I received notifications that my forwards to gmail are creating backscatter spam to a third party. As I have a zero tolerance for spam, I want to close this loophole. I don't, to be honest, quite understand how it works - I think it's gmail getting the message and instead of just refusing it, I think they're sending a notification to the third party.... meh. But either way, from what I've been told, the way to stop this is to disallow forwarders to gmail.

    Meanwhile, I did find a thread that said that if you create a forwader AND a mailbox and enable SpamAssassin, then it'll scan for spam and hopefully lessen the flow - but I want the flow stopped, not lessened. AND in that case you have to clean out the useless mailboxes periodically, so..... it's a terrible solution.

    Anyone have any ideas?

    There's no native feature that will block the actual creation of the forwarder in the cPanel interface, as discussed here:

    block forwarding

    You can open a new feature request for this functionality if you are not comfortable developing a custom script to implement this behavior.

    Thank you.
