[RndTbl] Shaw email - new woes

[Hartmut W Sager]

I have a simple solution - don't be dependent on the whims of your ISP for
mail servers.  I'm using Tucows/OpenSRS for my globally accessible
(authenticated) SMTP server, which also means I won't be rejected for
"relaying" if I connect my laptop to the Internet at some other premises
than my own.

Also, for good measure, I am using this same SMTP server at Gmail, where
(policy change in Sep 2014) any newly created "from" address requires you
to supply your own SMTP server (a BYOS policy - "bring your own server").

For a Tucows/OpenSRS reseller, that SMTP server costs $0.50 per month - a
negligible cost.

Regarding MTS, I believe they recently switched from MS
Live/Hotmail/Outlook to something else for their mail service offering (@
mymts.net).
