In some cases when you attempt to send mail you can experience an error similar to the following:
The connection to
the server has failed. Account:
Protocol:SMTP, Port: 25,Secure(SSL): NO Socket error: 10061, Error
This error usually indicates the failure of
youremail program to connect to port 25, the SMTP (outgoing mail) port.
One of the following is the likely cause of this problem:
- Your firewall blocks SMTP connections to an internet mail
server. Consult your firewall documentation or network administrator
- Your Internet Service Provider (ISP) does not allow SMTP
connections to an internet mail server. Most large ISPs now block
port 25 in an effort to prevent spam. If you believe that this is the
cause of your error you can configure your SMTP port from 25 to 8889.
