The message could not be sent because one of the
recipients was rejected by the server. The rejected e-
mail address was '(e-mail address removed)'. Subject 'message
from express', Account: 'mail.pontesquash.com',
Server: 'mail.pontesquash.com', Protocol: SMTP, Server
Response: '503 This mail server requires authentication.
Please check your mail client settings.', Port: 25, Secure
(SSL): No, Server Error: 503, Error Number: 0x800CCC79
 
You should contact the help desk of pontesquash.com because they are asking
the sender (you) to do one of the following.

1) logon to the server in order to send a message (use the same credentials
as your POP3/IMAP account)

or

2) Check your e-mail and then send the message. (Outlook sends and then
receives while most internet e-mail programs do the reverse.)

Since you didn't mention which version of Outlook you are using, it will be
difficult to let you know which to try.
