Many ISPs are beginning to block access to common SMTP server ports in an effort to force their users to use their SMTP server so that they may monitor and control users who are sending unsolicited emails.
If your ISP is blocking access to port 25, you may use our secondary SMTP server which is installed on port 26 by adjusting the settings in your email application to use port 26 for your SMTP server instead. Alternatively, you may also connect securely to our SMTP server over SSL on port 465.
If you find that your ISP is blocking access to all available SMTP ports, please contact them to request their SMTP server address and configuration instructions so you may use their SMTP server in place of ours.
Please note that you should always be able to send and receive mail through Webmail without issues even if your ISP is blocking access to our SMTP ports.
