Many ISPs (COX, COMCAST, ROADRUNNER, etc.)  now block the use of Port 25, which is the SMTP port, which may prevent you from sending email using our servers.

You may use our servers to pick up email and their servers to send email, which is a workable solution.  Please see your ISP's documentation or technical support group for what outgoing server to use if you wish to use this as the solution.

We offer alternate ports that users can use for SMTP that bypass port 25.

PORT 583
