Description
Describe the bug
Mail notifications don't have a Message-Id header. Although RFC 5322 doesn't say there MUST be a Message-Id, there are several reasons why an email should have a unique identifier, which is essential for
- tracking message threads and conversations
- detecting duplicate messages
- creating proper reply chains (along with
In-Reply-ToandReferencesheaders) - debugging mail delivery issues
- proper spam detection systems
Steps to reproduce
- Enable mail notifications on OC instance
- Share file with user
- Mail notification is sent
Expected behaviour
- an email containing a
Message-Idheader.
Actual behaviour
- Mail doesn't have a
Message-Idheader - receiving MTA also logs
