Hi... more than 1 month with a bugged EXIM version not running ok with simple SPF policies, while Exim developers published a fix months ago.... and no urgency at all.
I'm going to be pretty straight forward on this.
1. We removed this functionality in our version of Exim some time ago because of issues with the way it performed DNS Lookups.
2. We offset the responsibility for this behavior to SpamAssassin, where you have far more control, it's reliable and can weigh the scores or auto-delete.
3. You're using a customization that bypasses the methods which we have decided work best.
With that being clear I do hope you understand that the configuration you've chosen is not something that we provide or support which can sometimes take a back seat to issues with supported items and while this IS fixed in the current EDGE build of cPanel & WHM and you're welcome to update to it as of right now it has not been ported into a RELEASE version of the product and I don't have an ETA of when it will be. As soon as it is I will update this thread.
