I'm currently in the testing phases of using logsat.  So far I really like the product and will most likely purchase a license.  However there's on issue that's keeping that from happening.  I get a large amount of reverse DNS lookups that are being quarantined.  But when I turn around and do a dig on my DNS server it provides me with a PTR record for the IP in question telling me that SpamFilter ISP is blocking mail that should be passed through.

What is the specific criteria that spamfilter needs to be supplied for reverse DNS?

Paul,

If you can please post a couple of SpamFilter log entries that show what you think are the false positives we'll be glad to take a look.
