Using Windows Live Mail on Windows 10. No problem for years. Suddenly, Send/Receive refuses to deliver any email.

Error message:  Your server has unexpectedly terminated the connection. Possible causes for this
include server problems, network problems, or a long period of inactivity. Account:
‘comcast.net’, Server: ‘comcast.net’, Protocol: POP3, Port: 995,
Secure(SSL): Yes, Error Number: 0x800CCC0F

    Comcast seems to have suspended the SSL requirement. Simply fall-back to the unsecure (insecure?) settings:
    POP3,
    mail.comcast.net port 110, no SSL, (POP3)
    smtp.comcast.net port 25, no SSL, (SMTP)

    1) Start Outlook Express or WLM in the normal manner
    2) Click Accounts >> Properties
    3) Advanced tab
    4) Clear both SSL boxes This server requires a sequre connection (SSL)
    Click Use Defaults (this should set Outgoing port to 25)
    Make sure Outgoing mail (SMTP) has port 25.
    Make sure Incoming mail (POP3) has port 110.
    Make sure both SSL boxes are still blank.
    6) Click OK.

    Then perform a Send/Receive. This occurred on the day the NSA changed it’s spying rules, so it could be related. Maybe the settings can be restored in a few days…

    If these SMTP settings prevent sending, try changing the outgoing only:

    •Incoming Mail Server Name: mail.comcast.net
    •Incoming Mail Server Port Number: 110 (POP3 Without SSL)
    •Outgoing Mail Server Port Number: 587 (POP3 With SSL)
