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
'test@my-domain.ca'. 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.

Over the last few years, more and more ISP's have started to require their subscribers to use their SMTP server to send mail.
This
allows them to monitor spammers, and help to reduce to the overwhelming
amounts of spam and exploitation that occurs daily with email.
In this case we suggest you set your outgoing mail server to exactly the same setting as you use for your ISP.
If you are not certain what these are: check on this list below for your ISP.
Provided with each ISP that blocks, is their respective SMTP server setting.
This list has been compiled by the Support staff over the last year. It
is not an complete list of ISPs that require that their clients use
their SMTP servers, however, it is as accurate as possible at this
time.
