I could send emails on Friday, but yesterday, could not and have not been 
able to today. Message I get is this:

 Account: 'Windows Mail', Server: 'pop-server.satx.rr.com', Protocol: POP3, 
Server Response: '-ERR An authentication mechanism MUST be entered', Port: 
110, Secure(SSL): No, Server Error: 0x800CCC90, Error Number: 0x800CCC18

Have not had any problems until yesterday. Did a new update cause this?

Why has this happened?

Thanks in advance for your help.

Go to Tools, Accounts, select that mail account, Properties, Servers.
Make sure that "Log on using Secure Password Authentication" is not enabled.

So did you try the suggested fix of mine you quoted below?
It sure looks like you have Secure Password Authentication enabled.
It shouldn't be.
