Error Number: 0x800CCC0E

The connection to the server has failed. Account 'mail.yourdomain', Server: 'mail.yourdomain', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10051, Error Number: 0x800CCC0E.

If you receive the above message when trying to send email, the chances are that your ISP is stopping you from sending email out. A growing number of ISP's are now blocking port 25 (which is used for outgoing SMTP mail) to help prevent spamming. At this time we know that AOL, Orange and Wanadoo have this in place.

To bypass this, you must open your email client and change the "Outgoing SMTP Port" from 25 to 26.

If you are using the SSL ports for sending mail you will already have this set to 465, whch is not usually blocked by your ISP, so if you receive this error and you are using port 465 please raise a support ticket.
