I've been wrestling with this a bit.

A few questions:

1. How do I set up a caching nameserver?  Can someone throw me a link?

2. I've searched high and low, but I can't find the bayes DB location.  
I never explicitly set it up, but it's apparently running...

Output of mailscanner --lint below:

spacecowboy# mailscanner --lint
Read 759 hostnames from the phishing whitelist Checking version
numbers...
Version number in MailScanner.conf (4.58.9) is correct.
MailScanner setting GID to  (125)
MailScanner setting UID to  (125)

Checking for SpamAssassin errors (if you use it)...
Using SpamAssassin results cache

SpamAssassin reported no errors.
Using locktype = flock
MailScanner.conf says "Virus Scanners = auto"
