[MlMt] Configured SMTP server is broken?

[Brenda Bell]

I have multiple accounts configured and up until today, sending email 
via a specific SMTP server based on the selected from address was 
working flawlessly.

As of now, when I try to send email from my gmail account, it’s using 
the wrong SMTP server which is making the send fail. Not seeing anything 
in the activity viewer that would indicate what’s wrong.

What else can I check?
