Configure your MTA properly and the problem will go away.

Set it to make decisions after it receives the HELO, MAIL FROM and RCPT 
commands. That way you have the data you need and can decide accordingly.

You could also consider setting up per user filtering such that those 
particular users have fewer checks applied.

Note however that if you do this those users will end up creating problems 
for the other users when they accept virus/worm infected messages.
