According to Webster:

Diatribe: a bitter and abusive speech or writing

Len, that sounds a lot closer to what you are doing than Scott.  As soon
as Scott posts a message you disagree with you jump in with teeth bared
and wit sharpened.  Anyone other than Scott and you simply respond in
your usual curt manner.  It doesn't have to be incorrect for it to be
FUD, and just because you think it is incorrect doesn't make it FUD.
The language you use and the manner of your personal attacks DOES make
what you do FUD.

Most of this list respects what you have to say based on your experience
and helpfulness.  It is the same with Scott.  Len, **YOUR** abusive and
virulent FUD helps no one.

99+% does not equal 99%, but it's close enough for Scott FUD

For every IP of a legit MTA with a PTR in subscriber style, there must
be 1000 IPs with infected machines doing direct-to-MX abuse.  0.001 of
subscriber IPs are legit mail servers. As small as that is, there is
another fractional multiplier.  And whatever the fraction is, it's
decreasing as many  more new, infected subscribers are increasingly
populating these networks world-wide, at much higher rate any increase
in legit MTAs.

In addition to the number of IPs is the msg volume.  Anybody who is
running a mailserver on a cable or DSL is almost always a small
organization with a small volume 10's or 100's of outbound msgs per day.
In comparison, an infected PC spewing abuse can send out 100's or 1000's
of msgs per hour.  Roughly, the volume of legit msgs vs abuse msgs is

0.001 of subscriber IPs are legit x .01 of total volume from subscriber
networks = 0.00001

0.00001 of your 300,000,000 = 3000 legit msgs in 300,000,000 abusive
msgs.

And any MX that adopts a policy of blocking subscriber networks by PTR
can easily identify its  set of legit MTAs and whitelist them.

A huge weakness of Imail/declude is that they can't block by PTR
hostname.

A huge weakness of declude is that they it wastes bandwidth, by
accepting ALL msgs before they can be rejected.  Totally insane, when
the wasted bandwidth is often 8+ times greater than the legit mail/dns
bandwidth of legit traffic.

Total FUD, actually total BS.  You're using "%" (apples) vs "millions" 
(oranges) to make your bogus point, which is no point at all.

>Like C/R, it is FUSSP (see

FUD again.  Because subscriber networks are so universally infected and
abusive, blocking by PTR hostname is effective for all MXs.

>everyone does it.

FUD.  Blocking by subscriber networks by PTR hostname is extremely
effective and efficient.
