E-Mail: Spectrum -- Time Warner Cable -- RoadRunner

NOTE WELL: The subscriber certificate for Time Warner's mail.twc.com
POP3 server expired today without a new certificate being installed.
Secure access to E-mail from the server via an E-mail client (e.g.,
Thunderbird) is not possible. Appearently, Web-mail access still works.

You should be able to switch back to normal
email access for the time being. Most servers
still provide that. Typically port 587 for SMTP
and 110 for POP3. Then switch the setting for
connection security to "none".

There are 3 possible connection types, any
or all of which may be supported by a given
server. Basic is usually 110 and 587. STARTTLS
can be on any port because the client program
negotiates encryption after contact is made.
TLS (In TBird it's "SSL/TLS" even though SSL
is an outdated term.) is usually on port 465 for
SMTP and 995 for POP3. TLS makes contact
encrypted so it has to go to a port that can
handle that.

You can check your ISP website to see whether
they still support non-encrypted email and what
the settings should be.

It appears that this has been fixed. However, this incident indicates a
serious lack of attention to issues of secure Internet.
