would that add an overhead to the main server that is busy as it is
since it did not pickup email in the first place. What if prim is not
available?

I really like this!! I would like to try it. In fact, I do have up to
date mysql database with all valid email addresses maintained by the
control panel. The format is not strait forward and would require some
script to process, but I would be really interested in writing a small
perl script that I can hook to exim and get it executed for each
incoming email and let it decide a if email should be accepted for a
delivery. Is this possible? If yes, can you refer me to some example?

This is actually sounds like not such a bad idea. I will plan it for a
weekend. This way I will have more time to deal with any kind of crises
might come up, plus, the general critical mail traffic on weekend is not
as high as during the regular weekday.
But I still want to try script first! I would probably use it regardless
of version of exim I use.
