Spammers are constantly changing their tactics to overcome the latest measures in place to stop them. Keep in mind that this is a business that generates millions of dollars of revenue per year as a whole; it's in their best interest to try and circumvent any and all anti-spam efforts.
That being said, I'm sure that greylisting will be around for some time, and it is still a very useful implementation upon anyone's mailserver. Just like any other anti-spam effort, it's effectiveness will wane over time, but greylisting should always be used in conjunction with other anti-spam methods, and not be singularly relied upon. Policyd has served me well on my own mailserver, and also upon the mailservers at the company I work for. I look forward to any further projects Cami works upon that will help reduce the amount of junk I receive in my inbox. :-) E. > Here's a philosophical question... > > If the SpamBots are really adapting and they are paying attention to > Greylisting, then are greylisting's days numbered? > > Also, I saw another thread recently about changing Policyd's > rejection number to a "proper" temporary failure.
