I do really appreciate the help, and hope you'll forgive my naïveté in electronic mail matters, but there are still a couple of things that aren't clear... probably because my mail client is dated and terminology may have changed.
You mention, "Requires SSL: Yes." Well, I have no such option listed, instead here are the choices in Windows Live Mail under the Servers tab:
Log on using clear text authentication
Log on using secure password authentication
Log on using authenticated POP (APOP)
Additionally, under an Outgoing Mail Server heading there is a checkbox:
My server requires authentication
...and then under Settings for that are two choices:
Use same settings as my incoming mail server
Log on using:
Account name
Password
Other than these differences in terminology (I hope!), the other instructions you provided can be accommodated. Thus my question boils down to, is the 'SSL: Yes' you mentioned something I've listed here? Sorry to be such a nuisance.
