Not exactly. AFAICT what they do is issue 4xx errors in case any
mailbox gets over a certain threshold of bouncing mails. There's also a
very obvious looking VS14-RT5 code stuck onto the bounces.

A little bash or perl to pull the queue ids for those mails out of the
mail queue, and feed them to exim -Mrm, has been known to trash a lot of
spam (and in some cases, virii), stuff that'd anyway stay in your queue
or double bounce at some point of time or the other.
