[nylug-talk] Mail servers on dynamic IP addresses soon to be shunned nearly everywhere.

[Ron Guerin]

Just a heads-up for our listmembers....

MAAWG is the Messaging Anti Abuse Working Group.  It seems that if
you're running a mail server on a dynamic IP address (and no one cares
if your dynamic address never changes, that's completely irrelevant),
and not using a smarthost, your mail isn't going to be going anywhere,
Real Soon Now, because the MAAWG members have decided to no longer
accept mail coming from IPs their owners have listed as dynamic and/or
as IPs that are not permitted to run servers by service agreement (these
are generally the same dataset).

FWIW: NYLUG does not presently prohibit dynamic IPs from sending mail to
its server.

>Are there any reasons to block mail other than your own opinion ?

Yeah, the fact that within a very small fraction of a percent, it's
all spam.  I just got back from the MAAWG meeting in San Francisco,
with people from big ISPs all over the world.  Anyone who is still
arguing that we should accept mail from dyamic IPs can stop arguing
now.  We're not going to, whinging won't help.

Yes, why?  You planning to stalk them or something?

The ISPs and mail providers there included AOL, Bell Sympatico,
Bellsouth, Charter, Earthlink, TW/Roadrunner, Verizon, AT&T, Cox,
Comcast, Cablevision, France Telecom, Rogers, Telus, MSN/Hotmail,
Cingular, Sprint, Outblaze, Yahoo, and a bunch more I don't remember
off hand.

If I were you, I would be sure not to do business with any of them,
and not to accept mail from any of their users.  That'll sure teach
them a lesson.

R's,
John
