As part of our efforts to minimize mail deferrals, we will be disabling Port 25 for email clients (such as outlook, thunderbird etc) on some of our email only server accounts. Port 25 will be disabled in the third week of January for those selected mail servers and we will be notifying the administrative and technical contacts we have on file about these changes.
Port 587 has already been enabled as a replacement and we encourage you to adjust your mail clients to enable Port 587 for SMTP connections.
To change the SMTP Port you need to enable Port 587 in the following way:
Coupled with SPF and DKIM that we launched early in 2010, disabling Port 25 will help ensure a more stable and seamless email experience for your mail accounts.
If you have any questions about these changes, please contact us for details.
