[tlug] Microsoft CAN do it right!

["Stephen J. Turnbull" <steve@example.com>]

Hey, all, don't know who needs to know this but ...

Thursday, I did my first IP delisting at an Email Oligopolist.
Microsoft.  Very professional.  I prefer not to praise Microsoft, I’d
rather bury it, but this was slick.

OK, it's been >48 hours and I'm 3/3 on addresses that complained about
my IPv4 address.
You NEVER gotta hand it to M$FT, but this one they did get right.

Spamhaus though needs to be fscked off the 'net for discouraging IPv6.
Linodes get 1 free /128, but Spamhaus blocks everything in a /64 if it
blocks anything in a /64, and there's no relief.  Fortunate-lee I have
the key (old people may know what I mean), or ackshually Postfix
allows you to set outgoing mail to IPv4 only.[1]  So

                        #5alive, we be jammin'


Footnotes: 
[1]  The docs are good, but discovery was like dentistry, so:
master.cf: smtp - - - - smtp -o inet_protocols=ipv4
