I was able to send outgoing e-mail via Thunderbird client to

Customer Question

For years I was able to send outgoing e-mail via Thunderbird client to a vast number of folks via a comcast SMTP server, since I'm on their network. At some point during 2015 four of my friends, all of which are in the domain, I could no longer send messages to. Does any one have a clue?
Here are my smtp acct settings
port 465
username ...........
auth. Method normal password
Connection security SSL/TLS
I would get the following e-mail sent back to me:

Hello, welcome to JustAnswer my name is ***** ***** I'm one of the experts who will be assisting you today.

Sorry to hear you're having trouble with your computer.

Is it just those 4 friends you cannot send emails to?

May I start a remote session so we can work on the problem together from your computer?
