Did NOT make ANY changes to anything at all. I use DeamHost for my Web Host and E-mail Service. Once in a while, your Mail.app (sometimes referred to as 'Apple Mail' or 'Mac Mail'), stops receiving new mail. You may be able to verify that you are getting new mail via webmail, another email client or computer, or even via a mobile phone. When this happens, the fix is extraordinarily easy! If you can’t open Mail on your Mac. If you try to open a version of the Mail app that can’t be used on your Mac, an alert message is displayed. Make sure the version of Mail you’re trying to open is located in the Applications folder. In the Finder, click Applications in the sidebar, then double-click Mail.

It was pretty simple in the end (took 4.

1. Check Internet Connection.

If you find that you’ve not been getting any new emails in your Mail app then it’s important to first make sure that your internet connection.

Here’s how to check the status of your Internet in macOS Catalina:

First and foremost, quit any apps that are open and then connect to your Wi-Fi network.
Next press and hold down on your Option (Alt) ⌥ key and then click to open Wireless Diagnostics from the Wi-Fi status menu . You will need to enter your administrator name and password when prompted.

Help! I don’t see the Wi-Fi Status Menu. How do I get it to show up?

If you don’t see the Wi-Fi status menu, then simply go into your Apple menu > System Preferences > Network > Wi-Fi. From there check the option to “Show Wi-Fi status in the menu bar“.

Now the Wireless Diagnostics will begin analyzing your wireless environment.

To diagnose whether the Wi-Fi problem is intermittent, then when prompted with the below screen, choose to Monitor my internet connection. This helps in identifying if there are any hidden fallacies with your internet which may be the reason causing the Mail app to not work.

If you find that there are no issues with your internet connection but the Mail app was still able to not download it, then proceed to the next method.

2. Check Mail Authentication Logs.

It is also possible that you have authentication problems when you log in to the email server. This happens usually when you update the password of your email directly on the website. There is no way for the Mail app to know if you’ve changed the password from the website without throwing an authentication error.

However, if you haven’t made any changes, then it could be that the file which holds all your authentication data (username and passwords) may be corrupted. To fix this you need to update the data of your account that is configured in the Mail app.

For both of the situations discussed, the following steps will help patch up any authentication errors and subsequently help update the Mail app with the right credentials:

Go ahead and launch your Mail app in your macOS Catalina.
Then click the Window option in the main menu and click Connection Doctor option.
Now if there are issues with the connections, click the Log Connection Activity option and try again. Click on Show Logs option to check issues details of the issues.

Next, search for the Keychain Access app and launch it.
Then type in @ symbol in the search bar and press enter.
Click on the account to highlight and delete the password from your iCloud keychain by doing right-click and click on Delete.
Go back to your Mail app, click on the Preferences option, and then Accounts.
Now delete your email account and add it back again with the correct details.
Finally, restart the computer and relaunch the Mail app.

Now that you have updated the data of your email account in the Mail app, you will be able to connect to the server with no issues. But if you are still not able to download your new emails from the server, proceed to the next method.

3. Disable or Uninstall Any Third-Party Security Software.

There is a chance that your anti-virus software or firewall application on your Mac is not allowing you to download the email files to your computer. Some third-party security software does not have that configured by default. To be sure, disable (or uninstall) all unnecessary antivirus software and try to download your email again.

Once you’ve done that, you will be able to download your email files successfully. This solution has proven to have worked for a couple of users who managed to get their Mail app working after disabling their antivirus software on their Mac.

If the issue with the Mail app is fixed and you’re deciding to re-enable back the antivirus software, then make sure to contact their technical support beforehand and explain the situation. You will need to ask for their assistance on how to configure the software so it will not block the email download process responsible for the Mail app.
