Some major ISP's (such as AOL,Sympatico,MSN,etc) block outgoing email.
If you're using one of these providers, or you receive this error when trying
to send an email: The message could not be sent because one of the recipients was
rejected by the server. The rejected e-mail address was
'email@example.com'. Subject 'Test', Account: 'my-domain.ca', Server:
'my-domain.ca', Protocol: SMTP, Server Response: '550 5.7.1 ... Relaying denied. IP name lookup failed [X.X.X.X]', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79 Click here to run a port test to find an available port.
Click the Advanced tab. Change the Outgoing mail (SMTP)
port from 25 to 26 or use or 2500 or 587 (or any port that the port test showed as available - it varies by ISP).
Click Ok, then Close.
