Spam blocking like Spam Arrest

[Peaches]

I cut off the email for all but my main domain and it has cut my spams from 3K a day to 300 a day. YIPEE! BUT, I always want better

I'm looking for something that's domain specific where they have to verify, i.e. peaches at onlinebeach dot com, webmaster at onlinebeach dot com, 123456 at onlinbeach dot com and every other bogus front the spammers can come up with. Does something like that exist? And can you put "good" incoming addresses in there for approved newsletters and such?

I think I'm going to have to use Spam Arrest for my 3 Mindspring addresses, so if anyone knows of something where I'm not paying 3 times, that would be welcome too

Again, I'm not looking for anything EXCEPT the email verification like Spam Arrest. My filtering takes care of the other crap.

Thanks!!!!!!
