Forwarders and spam scanning - no solution yet?

stormy
I would like to bring up a long-standing issue (there's tons of threads), just to see if there's any progress, and maybe if there's a feature request that we could all vote on. Quick summary of the problem: If an email forwarder is set (and customers, for some unfathomable reason, LOVE forwarders), all inbound email is forwarded with no spam scanning at all. All of a sudden your server is sending real, nasty spam to Gmail, AOL, Hotmail, Yahoo etc. It doesn't take long for the server's reputation to be affected. Workarounds? -The paid Rvskin theme does have a feature to block forwarders to select domains. However, customers are not happy when they find out! -Yes, I know I can tell customers to set up a POP account, and then check POP from Gmail, or whatever. This doesn't really work. -Yes, I know it's crazy to want to forward your emails to Gmail after buying a hosting account under your own domain. But people do it anyway. We need a real solution. It's as easy as having SpamAssassin scan emails before they hit the forwarder. I don't know if the technical details are complicated, but I think cPanel has the resources to deal with this once and for all. It's better for everyone: -Our server's reputation is kept intact. -Our server's mail queue (and load) is decreased, since it doesn't have to deal with forwarding spam. -Customers are happier. -The receiving end of the forwarders, whoever it is, is happier too. Are there any downsides? Please enlighten me.

    Thanks Michael :) No further comment from cPanel? Is there a technical reason why email is not forwarded after it goes through Spamassassin? Edit: here's the feature request, in case anyone is interested:

    Here's a solution I found. I discovered that SpamAssassin marks the header of even forwarders. Since it whitelists an email coming from the same domain, I used this workaround rule. Make the following filter/rule per account, or Global if you want all spam going to just one single Junk folder. Rules Any Header contains X-Spam-Status: Yes Headers of even forwarders contain the words "X-Spam-Status: Yes" so they will get marked, even if an actual email account for the forwarder doesn't exist!I hope it works for you like it did for me!

    Well, the feature request worked, and it's now "in progress". :) It should be ready by early next year, if I didn't misunderstand the release calendar.

    Yes, it's scheduled for cPanel version 11.48. There is no specific date available on it's release, but Q1 2015 would be the expected timeframe. Thank you.

    I've been wrestling with this issue. The feature is eagerly anticipated. However I have discovered that if you enable a POP3 account AND a forwarder to gmail... with spam assassin enabled... AND within WHM you tick Service configuration: Exim configuration manager: ACL options : SpamAssassin" reject spam score threshold (5.5?) (Reject mail at SMTP time if the spam score is greater than this number. (positive or negative, single digit after a decimal point allowed)) This seems to work. The downside is that the POP3 account will fill up and need to be emptied. and also ticking this ACL option seems to disable spam box and all spam is just deleted. Check it out.
