Why unread mail marked as read plesk

A frustrating issue!

When you mark an email as "unread" in Plesk, it's possible that the email client (e.g., Outlook, Thunderbird, etc.) or the email server (e.g., Postfix, Dovecot, etc.) is not updating the email status correctly. Here are some potential reasons why an unread email might be marked as "read" in Plesk:

  1. Email client issue: Check your email client settings and ensure that it's not configured to automatically mark emails as "read" when you open them. You can try disabling this feature or using a different email client to see if the issue persists.
  2. Email server configuration: The email server might be configured to automatically mark emails as "read" after a certain period of time. Check your email server configuration files (e.g., Postfix's main.cf or Dovecot's 10-mail.conf) to see if there are any settings that could be causing this issue.
  3. Plesk email client: Plesk uses a built-in email client to manage emails. If the Plesk email client is not functioning correctly, it might mark emails as "read" incorrectly. Try restarting the Plesk email client or checking for updates.
  4. Email filtering: If you have email filtering rules set up in Plesk, they might be causing the issue. Try disabling email filtering or checking the filtering rules to see if they're configured correctly.
  5. Email storage: If the email storage is full or almost full, it might cause issues with email marking. Try freeing up some space in the email storage or increasing the storage limit.
  6. Plesk version: If you're using an older version of Plesk, it might be experiencing issues with email marking. Try updating to the latest version of Plesk to see if the issue is resolved.

To troubleshoot the issue, you can try the following:

  1. Check the email client logs to see if there are any errors related to email marking.
  2. Use a different email client to access the email account and see if the issue persists.
  3. Try marking the email as "unread" again and see if it stays marked as "unread" for a short period of time.
  4. Check the Plesk email client logs to see if there are any errors related to email marking.

If none of these troubleshooting steps resolve the issue, you may want to contact Plesk support or a system administrator for further assistance.
