connection caching, but because we've been treating it as attacks, we've
been handling it differently than if it was a legitimate, but unwanted,

+1. I felt the same way.
Maybe an info or BCP document would be useful
I'm on the fence on how it can be approached since opening up this
door will most likely require some cleanup of related topics pointing
to 5321 and still having 1 conflict with 821, starting why QUIT is
required in 5321 and not in 821. And if you recall not too long ago,
the long debate about not slowing down the DATA EOD response. Well,
that concern should be moot now with the CS client holding times
negating all efforts to speed up DATA EOD filtering. :)
