Spamassassin per email account configuration override


I am looking for a method to change a mail users spamassassin config to be less sensitive to spam, ideally everyone that sends mail to her would have clean IP’s and setup their rDNS correctly but alas this is not the case. I dont want the entire domain to be less sensitive just this one account. This server only has one domain on it.

Where would i find some instructions on doing this?

Im using Webmin 1.9 on CentOS 6.1
