Mozilla Thunderbird will automatically obtain the rest of the mail settings. However, these settings aren't always correct. So you will need to manually change them to the correct settings.

Step 6:

Fill in the rest of your mailbox details, which are provided by your Internet Service Provider and click Done. See example below.


Step 7:

Leave message on server option is automatically selected when you add an E-mail account to Mozilla Thunderbird. To change these settings, click on Advanced config as seen below.

Advanced Config

Step 8:

Select Server Settings on the left hand menu. This will then bring up the settings options where you can change you leave message on the server options depending on your needs. See options below

  1. Recommended setup: Make sure that Leave messages on server is checked. Then change the number of days you want to leave the messages on our server
  2. Multiple Devices: Make sure that Leave messages on server is checked. You can either set the number of days you want to leave on our servers or alternatively, uncheck for at most checkbox completely.
  3. If you check Until I delete them, then the messages will be deleted when you delete them in Mozilla Thunderbird. This may be useful if you're trying to keep multiple devices in sync without IMAP, but you shouldn't choose it if you're leaving messages on our servers to be backed up.

Please Note: If you leave messages on the server forever, it can eventually slow down your mail connections and use up your disk space allocation. So we recommend choosing a number of days that's long enough for you to be able to read the messages in your other mail programs (or Webmail). In terms of performance, even using a large number such as 365 days is better that not checking this box.

Step 9:

Once you are happy with your Leave message on server setup, click Ok.

Step 10:

This next step may or may not occur. A Warning may pop up as seen in the below image.

This is nothing to worry about. It is only informing you that your incoming and outgoing mail servers are not using encryption. This encryption is not always required, depending on the ISP

Simply tick/check the I understand the risks checkbox and then click Done to complete your mailbox setup.
