I've actually noticed some slightly strange behaviour in exchange
regarding the message tracking feature. We had a problem where if a
message was quarantined, it would send the decontaminated message out.
If I went and located the message in quarantine and copied it into exims
delivery queue, exim would pick the message up and deliver it, but the
exchange server would have no record of having received it.

I was never able to tie this down to anything specific, and we ended up
fixing it by not sending through notifications rather than the defanged
message. Just something to be aware about if you are working on this.
