Pellux Network Email is hosted by a 3rd party for optimal compatibility with other mail servers. The downside to this is you are not able to reset your password through the Pellux webmail interface. Here is how to do so
First, you must login to your email account through the cPanel interface by going to https://gator4017.hostgator.com:2096 in your web browser.
Once logged in, click "Webmail Home" on the upper right corner (it's a logo with the letters CP)
Next, click the dropdown with your email address and select "Password & Security"
Change password on the final page and you're done!
