I have a question about how that works, Philip... Does the memory allocation
occur when reading in the filter file or only when the particular rule(s) are
reached?
I have a lot of very effective spam scoring rules in place, but many of
them refer to $message_headers, which I gather is the main problem. I'm
wondering if it would help to exit the filter early under certain
circumstances, but if the memory allocation occurs as it's read in then
it probably wouldn't.
Is there any way we can get a patch to change the way this works in 3.35?
(wishful thinking)
