We've had good luck with it. Anytime we see a address that isn't in the list we add it and so do tons of other folks. It really does't do anything to slow our mail down... just a big ol' postfix map. postfix is super fast. antivirus scanning is the limiting factor in mail delivery usually. If you environment is already at capacity then you might have issues, but other than that i doubt you would see any issues. Joe Roger Safian wrote:

We loop outgoing mail thru another postfix instance to filter based off this project's list of phishing reply addresses. If you mail to a known phisher, your mail gets dropped. good protection.Any idea what the impact of using this has on the timeliness of mail delivery? With phishers being able to choose almost any return address, this seems like a galactic scale game of whack a moll. ;-) I worry that our servers couldn't handle the additional load.
