Debian Sarge, MailScanner, Exim, Spamassassin

[Dawson, Alan]

Hi,  I'm in the process of setting up a MailScanning gateway using Debian Sarge, MailScanner, Exim, ClamAV and Spamassassin.

Exim runs as user Debian-exim  and group Debian-exim so I altered the Run As Group and Run as User to those also.

Should I alter the 

SpamAssassin User State Dir = 
To be /home/Debian-exim/ ( or similar writeable location by Debian-exim )so that SpamAssassin can place its bayesian and auto whitelist stuff etc somewhere ?

Thanks
