This tutorial assumes you've already created your new email account in your web hosting account..... typically through your hosting control panel.
Now let's learn how to setup that new email account in Thunderbird, so you'll be able to send/receive emails to/from that new email account from here.
1) Start by clicking the Tools link here.
2) Then click Account Settings...
3) The Account Settings window appears.
4) Click the Add Account button.
The Account Wizard windows opens.
5) Make sure the Email account option is selected.....
6) Then click Next.
7) Enter Your Name as you would like it to appear in the From field of outgoing emails.
8) Then enter your new email address here.
9) Click Next.
Now you have to enter your Incoming Server (POP) setting, which would have been provided to you in your welcome email.
Typically, the Incoming Server (POP) setting is simply mail.yourdomain.com, where 'yourdomain.com' is to be replaced with your own domain name.
10) Choose POP3 for the incoming mail server setting.
11) Now enter your Incoming Server (POP) setting here.
12) Then click Next.
13) Now enter the email username as provided to you by your hosting provider..... this may be the entire email address (email@example.com), or just the username prefix (john).
14) Enter your username again here..... your outgoing username is typically the same as your incoming username..... unless you're using a different SMTP server (more later).
15) Click Next.
16) Enter a Name for this new account.
17) Then click Next.
18) Click Finish to complete the wizard.
We're almost finished! But first let's go finish configuring our SMTP outgoing mail server.
19) Click the Outgoing Server (SMTP) link here.
20) Click the Default SMTP server here.....
21) ..... then click Edit.
22) Enter your Outgoing (SMTP) server setting in this box here..... it should have been provided to you in your welcome email.
Depending on your ISP (Internet Service Provider), you may not be able to use the SMTP server setting provided by your hosting provider; you may have to use the SMTP server setting supplied by your ISP.
If you are unable to send emails from your new account after it's setup, try changing this SMTP setting to that provided by your ISP, and try again.
23) Click here to enable Server Authentication (which my or may not be required)..... then enter your username.
24) Click OK when finished.
That's it! We've successfully setup an email account, and can now start sending and receiving emails to and from that account, from Thunderbird.
25) Click OK.
This is the end of the tutorial. You now know how to setup an email account in Thunderbird. Remember that you also have to create that email address in your hosting account before it will work.
