Set Outgoing Mail Port to 366

Your computer communicates with the internet using connection points known as ports. Certain ports are commonly used for specific types of communication. Outgoing email is usually routed via port number 25.

As an anti-spam measure, many Internet Service Providers now block port 25 for any traffic trying to access a third party email server. This stops you from sending mail through our server (and leads to error messages and your outgoing messages just sitting in the outbox).

Fortunately, there is a way around this problem by changing the port number used for sending email on your computer. Please select the email application you use from the list below and follow the instuctions provided.
