Random tagging of incoming mail

This behavior may be observed in other mail clients but was first observed in the Mozilla Thunderbird client, this specific issue has to do with mail being tagged as important automatically with the user not setting this. 

In the Doom Networks environment, check if you have access to the Doom Networks Nextcloud instance. If yes then follow the below steps to disable automatic mail tagging:

1. Open Nextcloud and login.

2. Once logged in, open the Mail application

3. In the bottom left hand corner click on Mail Settings

4. In Mail Settings uncheck the second check box for Automaticall classify importance of new email.

This change should save automatically and stop the auto tagging in mail. Note: This is a known issue and is Nextcloud mail application issue and not a email client issue. https://support.mozilla.org/en-US/questions/1344965
