pop is an incoming mail protocol, so my guess is you have your account settings incorrectly configured. Could you please do the following:
  1. Open the menu Fx57Menu > Help > Troubleshooting Information, then click Copy text to Clipboard.
  2. Open a reply to this post, and paste in your troubleshooting information.

Today, my ability to send e-mails is all of sudden working again - without me changing anything. Perplexed but pleased.

I hope I got it all because when I copied it, I was given the choice to paste it, which created a list that was too long to submit, so I have edited out some of the white spaces. Thank you, Mike. mike.lennard876@gmail.com

'Incorrect greeting' means the authentication is incorrect for the account. You currently have authentication = none for both gmail accounts' outgoing servers. Tools/Account Settings, Outgoing Server (SMTP) at the bottom of the left pane, Edit the smtp servers for the gmail accounts. Change the authentication for the POP account to 'normal password' and OAuth2 for the IMAP account.
