This is an email address I made to collect exploding emails and post to the list with.
I even made a tiny PGP key and set mutt up for IMAP!
However, I don't seem able to connect to smtp.gmail.com on either the SSL port nor the TLS port, even over TOR or from public wifi, so I'm on a web interface still.
Still remains to try from a different device.
Via other means I found a different IP address that smtp.gmail.com can resolve to than the ones it does here. When I use that IP address, I can access the SSL and TLS ports.
Meanwhile, the IP addresses my name servers give me do respond on the old cleartext port, but they give a header line for mx.google.com rather than smtp.gmail.com . Meanwhile, mx.google.com does not resolve for me.
Below:

----- After writing the above I realized I was sometimes typing smtp.gmail.com and sometimes smtp.google.com . The former is presently working for me. The assertion something was wrong appears bogus right now.
