I have the problem that when receiving the email from the contact form, the emails are always grouped. This causes all the emails to be deleted when the user deletes an email. This is an Outlook and user problem. However, I would like to set the email to be unique in the communication. So subject should be the subject field and sender should always be the person who used the form and my server email.
What can I do to solve the problem on the server side.

- your web server is clearly not going to be on that list
- the email is immediately deleted
