Not authorized to login as specified user

I am configuring ssmtp and mutt on my Linux box and do believe I have it set up correctly, but I am gettign an error that seems to indicate that my account does not allow me to do this.  Is this possible?  Is there an account privilege that I need?

# pertinent settings:

mailhub=smtp.verizon.net:465

UseTLS=YES
AuthUser=<myemail>@verizon.net

AuthPass=<redacted>

Error from mutt command line:

ssmtp: Authorization failed (535 5.7.8 Authorization failure (Not authorized to login as specified user).)
Error sending message, child exited 1 ().
Could not send the message.

Thanks,

Steve

Problem solved.

I happen to be setup to use Verizon Yahoo! eMail, not regualr Verizon eMail.  I now know they are completey different.

The Verzion Yahoo! outgoing SMTP server is:

mailhub=plus.smtp.mail.yahoo.com:465

ssmtp/mutt on Linux works perfectly fine now.
