Setting up a new email account

• From the Tools menu, choose Account Options.
• Click the Add Account button to begin configuring a new e-mail account.
• Choose the Email account option, then click Next to continue.
• Enter your real name and email address as you would like them to appear on emails that you send, then click Next to continue.
• Choose whether you want to access your mail using the POP3 or IMAP mail protocol. For help with this option, see POP3 and IMAP email explained. For your incoming mail server, enter mail.yourdomain.com, and for your outgoing mail server, enter mail.yourdomain.com. You may need to change your outgoing mail server later. Once these fields have been filled, click Next to continue.
• Your username is your full email address, including everything before and after the @ symbol. Enter your email address in this text box and click Next.
• Enter the name you would like this account to be called. It is used only within Mozilla Thunderbird when referring to the account by name, such as when sending/receiving mail or changing account settings. Name it whatever you like, then click Next to continue.
• Click Finish to complete the setup of your mail account in Thunderbird. You will be prompted for your account password the first time you attempt to send/receive mail.

Changing your SMTP server address

• If you have issues sending email, but can receive mail properly, you may need to use your Internet Service Provider's outgoing mail server as described in Cannot connect to outgoing server to send mail. If you have been instructed by your Internet Service Provider to change your outgoing mail server address, you may do so by doing the following:
• From the Tools menu, choose Account Options.
• Choose Outgoing Server (SMTP) from the list at left.
• Enter the address your ISP gave you as the server name. Unless they instructed you otherwise, Use secure connection: should be set to No. Click OK to save your changes and exit this window.
