[Techtalk] re: filtering mail with spamassassin

[showercurtain]

I changed the spamassassin spam points scale from 6.5 to 6 a few days
ago and a lot of users complained valid emails are being quarantined 
:(

Could you explain in more detail how you did this? Eg: where the logs
are located; how you distinguished false positives from actual
spammers that were blocked when you checked the logs.  My
organisation really needs to implement something like this, so we can
at least say "Doing x,y,z resulted in a 10% decrease in spam".

Secondly - and this is a question for everyone - our spam folder
contains over 20,000 messages. How can I remove all messages except
those received within the last week?

Thanks
