Many customers are now finding that their ISP is blocking port 25 (the traditional outgoing email port) to any other provider except their own. This means, that whilst your ISP is being reactive about the amount of spam on their networks, i.e. stopping compromised machines blasting out spam, they are essentially forcing you to use their outbound email server.

This has problems if you are say, taking a laptop away from your ISP connection and need to send email.

3DPixelnet has always provided a ISP-neutral SMTP server that you can use. It simply requires a username and password. To get around the port-25 blockade on whatever ISP you happen to be on at the time, we have provided a secondary email port that always works on any network. This port is 2525 and can easily be changed from the default port 25 using our guides for Outlook, Thunderbird and Apple Mail.

We recommend that all customers with 3DPixelnet SMTP switch to port 2525 as we are finding many ISPs disabling port25 to protect their network from spam-zombie machines.
