Not really; this message isn't generated by a mail client, but by a mail
server. Sounds like you need to authenticate to your SMTP server in your
mail account properties....

I really think you need to verify your settings with your ISP. Perhaps they
require SSL, a different port number, etc - whose SMTP server are you using?
Try the one for the ISP (connection).
