Updates to your email server settings

What you need to do now

Make sure your settings are up to date by checking them against the details below.

The main difference (based on historical data) is that the incomming and outgoing mail settings now need to be authenticated with a password, rather than ‘challenge response’. You may also need to change the default outgoing SMTP port to 587 (rather than it’s default).

Your details should match up with either the IMAP or POP3 settings, depending on which connection you use. We always recommend the IMAP rather than POP3, so your emails are backed up to the cloud as well as your device.

If your details do not match after the legacy authentication method is disabled, you might not be able to authenticate and access your mailbox.

If this happens, please check that your settings match those listed in this support article. And of course, let me know if you need help.

Our standard and premium mailboxes can be loaded onto your device or through your mail client either with a POP3 connection or an IMAP connection.

By using an IMAP connection, you can have multiple clients simultaneously connected to the same mailbox. For example, you can have email on your phone, your tablet, and your computer, and when you delete a message from your phone, it will also be deleted on your other devices, for this reason we recommend using IMAP over POP3.

The way your device or mail client is designed may be different than how other programs or devices work, with different names for the same steps.

Your device or program should have detailed information on how to add and set up mailboxes onto the system, but there are general pieces of information you need to complete the process.

When selecting the account type, select IMAP.
Your User Name is your full email address.
Your Password is your mailbox password.

Notice: In August 2021, they announced that we are disabling legacy authentication on our mail servers and you should check your settings. This change does not mean you need to change your IMAP/SMTP server, only that you review the authentication method used.

As of Sept 2021, if you’re using an Apple laptop/desktop device (rather than iPhones which seem unaffected), due to some sort of glitch in the way the system has been updated, if your emails suddenly stopped to sync despite all the settings being correct as below, it’s likely you’ll need to:

  1. Backup your emails locally (just in case with IMAP. You MUST do this if using POP3).
  2. Remove/delete your email account from your email program.
  3. Restart your email program.
  4. Add a new account (using the latest email settings for the same account you had before). You’re likely to need to click through a few ‘Advanced’ options to change the port number and address, etc.
  5. Wait for your local account to sync with the cloud imap version, which may take a couple of hours depending on how many emails you have stored.
  6. If this looks to have worked, but all your email sub-directories are still empty after the syncing progress bar seems to have finished, you may need to start from Step 2 again.
