Email Clients: Mozilla Thunderbird
Follow the steps below to configure your Mozilla Thunderbird email client to work with your web-based email account:
Step 1: Open Thunderbird and select the Tools menu. Click the Account Settings tab.
Step 2. From the new window press the Add Account button, then E-mail account and click Next.
Step 3: Enter your name as you would like it to appear in the From: field for all outgoing messages and the email address which the others will use to send email messages to you. Click Next.
Step 4: Set the incoming server to be of type POP3. The address is your domain name.
Step 5: Click Next and type in the username. Please use the full e-mail account name. Example: firstname.lastname@example.org instead of you.
Step 6: After clicking the Next button, type in the name of the e-mail account as it will appear on your PC. Click Next, and then the Finish button.
Step 7: Click the Outgoing Server(SMTP) in the left pane. Use yourdomainname.com as Server name. Set the port to be 2525.
Then, check the username and the password and enter the full e-mail address as username.
Step 8: Click OK and you are done!
Make sure that you check your incoming e-mail messages before trying to send any. Our servers use the POP-before-SMTP scheme, which disallows sending messages without checking your mail.
