The server is probably down or you are seeing the result of network issues.

I do note It is gmail, but I've occasionally hit issues (rare, but true)

Are you trying to send from another gmail account or non-gmail account on this particular gmail smtp server?

No this is the same account I've had for like 8 years. Worked fine yesterday and now I can't send anything through Mozilla. I can log on Gmail with a website and send and receive fine.
