I posted this in the 3.5 thread, but maybe soemone here can test it:

I would like someone using Exim+Cpanel to test the .forward (dot-forward) file method
Here's how it works:
1. Create a file somewhere in your public_html directory /path/to/forum/admincp/subscriber_notify
this file should be readable/writable (666)
2.In your (subscriebr_notify) user home directory, create a
.forward file. The .forward file should have one line in it:
/path/to/forum/admincp/subscriber_notify
The theory is that Exim will start forwarding emails to that file.
Not sure what Exim considers "home" directory, so you may need to try creating it in different directories for that user account (subscriber_notify) to test which directory is the right place for .forward
Send an email to subscriber_notify, and check if it was copied to that file. Exim manual states that this should work, so let's keep our fingers crossed.
