Extremely bad. And if you want an example of how bad it can be: Google complaints about spamcop.net. People that use SpamCop as a single DNSBL (essentially a shared blacklist, since its a real-time community reporting tool) get lots of false positives. One persons spam is not essentially another's. ASSP, properly tuned, can work extremely well at keeping spam out. The most important, and essentially hardest part, is understanding how it all works. i.e. Understanding the components of spam, and how ASSPs features can be applied. Its tough; its not "turn-key"; but its our jobs. The defaults are good. Understanding the spam you get and how ASSP can be tuned, can make it exceptional. For instance: Something that I've often stressed in the past, is harnessing the power of using both the valid and invalid HELO filters. When used properly, the two together are far more powerful than just using the valid filter. The *vast* majority of all my spam is blocked because of HELO violations. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
