[Exim] Last question - Exim+Exiscan+ClamAV :)

Hi,

I tested Exim-4.20+Exiscan-4.20-09+ClamAV-0.60. Scanning and updating
work very good. I have a last question.

I set Exim and ClamAV user and group on 'mail'. Can you tell me,
is it a very bad idea ? Is there a ohter, better solution ?

Thanks for help
