Email Account Setup: Mozilla Thunderbirds: IMAP

Open up Mozilla Thunderbird and click on the "Create a new account" button in the right-hand pane.

Select "Email account" and click the "Next>" button.

Enter your full name in the the "Your Name" field and your email address in the "Email Address" field. Click the "Next >" button.

For Server Type, choose the "IMAP" option. For the name of the incoming server, enter "mail.sentinare.com". Click the "Next >" button.

Fill in the following fields as shown below using your own account information. Click the "Next >" button.

Enter a name for the account. This is useful if you have more than one account in your Thunderbird profile. Click the "Next >" button.

The last "Account Wizard" screen will allow you to confirm your settings. Click the "Finish" button when you have verified the information.

Now, select "Account Settings" from the "Tools" menu.
With a couple exceptions, the defaults in this window should be acceptable. To encrypt the network connection between your computer and the Sentinare mailbox server, check the "Use secure connection (SSL)" checkbox. This will ensure your privacy when working on public networks.
Next, click the "Advanced" button

Select the "IMAP" tab in the "Advanced Account Settings".
Enter "INBOX." in the "IMAP server directory" field. (NOTE the trailing dot "." after "INBOX".)
It is safe to leave the other settings at their default and click the "Next >" button.

The final step is for your outbound email configuration. Select "Outgoing Server (SMTP)" from the left-hand pane of the Account Settings window."
For "Server Name", enter mail.sentinare.com.
For "Port", unless you are a PostVault customer and have been given a different port number, enter 587. (Port 25 will also work but you will have less problems using 587 as it is becoming a best practice for public networks to block outbound port 25.)
Select "TLS" for "Use secure connection". This will encrypt the channel between your computer and the Sentinare server when you send mail.
Click "OK".

Now, to check your mail for the first time, click "Get Mail", which is the top left button in the main window.

You will next be prompted for your password. Enter it and check the "Use Password Manager to remember this password" checkbox. Please note: Your mailbox is accessible from the internet. Unless you select a strong password, the weakest link in the security of your email will be your password. Hopefully, you have chosen a tough one and change it regularly to prevent unauthorized access to your email.
Click "OK".

Click the "Finish" button.

Note: You will have to enter your password again when you send mail. You can use Password Manager to save that so that you don't have to enter it every time you send mail.
