That is, will it mainly stop spam, and not have much effect on non-spam? Will this stop enough spam to be worth the trouble of implementing it? Will it be easy to implement? Will spammers be easily able to change their behavior to bypass this spam stopper? Will system administrators be willing to use this option? My personal assessment is that this is not worth doing. But perhaps some of my colleagues will have different ideas. In any case, thank you for sending us the suggestion. -NWR To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
