Apple Mail Setup Troubleshooting

If an error, such as “Too Many Connections” or “Error 500”, pop ups when you try to set up your email using our Apple Mail tutorials, then there are a few different options you can try to troubleshoot the issue, depending on the mail program/client you’ve got installed on your computer.

Note: The default Apple Mail (or Mac Mail) application has several known issues, including not saving settings during setup, losing settings randomly and having issues with connecting several devices to the same email account. Unfortunately these are intermittent issues with the software itself, if you encounter these we recommend switching to Thunderbird or Outlook for Mac.

The first is try a different mail client to see if the error is related to your previous mail client:

Try a different mail program/client:

Mozilla Firefox offers their own mail client, called Thunderbird, which we recommend because it’s stable, easy to use and is a free email application. You can download Thunderbird without it affecting your current Apple Mail settings.

  1. Download Mozilla Thunderbird from their website
  2. Open Thunderbird on your desktop and click here to see instructions on how to set it up

The second suggestion is to disable the IDLE feature in Apple Mail. By disabling the IDLE feature, you close any active connections to our mail server alive. Netregistry limits the amount of active connections per IP.

How to disable the IDLE feature in Apple Mail

  1. In Apple Mail, select ‘Mail’ in the toolbar and then ‘Preferences’ from the menu
  2. Click [Accounts]
  3. Select the desired IMAP account
  4. Go to the Advanced tab
  5. Uncheck the ‘Use IDLE command if the server supports it’ tickbox
  6. Uncheck the ‘Include when automatically checking for new mail’ tickbox
  7. If this doesn’t resolve your issue, please contact our support team for further assistance.
