Attention: Eastlink Users (April 23 2007)
Eastlink is now blocking port 1025, our former unofficial outgoing mail server for server 3. We have changed this server port to 1075.
After talking with Eastlink, they block all users from port 1025 due to it being considered a dangerous port to leave open. Therefore, if your ISP blocks you from using an external mail server on port 25, you are free to change your outgoing mail server port to 1075 and it will work.
