What's an acceptable FP rate? Obviously varies from ISP to ISP to corps. The charter example I quoted was about 1500 rejects, and Scott says "maybe" 1 or 2 or 3 legit recognized in there.
I wasn't going to respond, but LEN YOU ARE LYING AGAIN!
You posted information about 134 E-mails, of which 3 used the primary domain of an IMail customer, and 2 appeared to be from legitimate mailing lists. Assuming that those 5 are non-spam, and that there aren't any other non-spams in there, that's a 3.7% false positive ratio, versus the .2% you are implying above (3 out of 1,500).
My recommendation gets trashed as lying and misleading for that FP rate? GMAFB
You lied and misled about the FP ratio. Should a lying and misleading recommendation not get a counter-response?
Applying subscriber blocking can done intelligently, although one wouldn't believe it from Scott's hammering.
Yes, it can be done intelligently. And with virtually no false positives. The two ways discussed are:
[1] Block every E-mail known to be from a subscriber IP, or
[2] Block every E-mail known to be from a subscriber IP that isn't a known legitimate mailserver, but only if the E-mail fails some other spam tests.
#2 has much more protection against false positives. Both have their benefits and drawbacks; I'll let readers decide which is best for them.
I don't go trashing and nannying Scott's posts...
Please do "nanny" my posts! If I lie or mislead people, you (or anyone else on this list) is welcome to let me know. I don't have a problem with that.
It is possible to get your point across without lying or misleading people. If you do that, you won't have these problems.
