George,

I hope this is relevant. Years back we had clusters of spam scrubbing
servers running declude. We found that the majority of spam was headed
to accounts that did not exist. However we were processing all
messages (wasting CPU) even though these end result was a failed
delivery regardless.

Do you have this type of checking? As in pre-checking if the user
exists before spam filtering.

Regards,
Edward
