In Re:amaze your conversations are threaded by the "In-Reply-To" email header, which is standard for modern email clients. If this header is not provided, Re:amaze will sort the thread by the "References" header on emails.
Lastly, If an email does not include either header, then Re:amaze will fall back to using the "Thread-Topic" header and subject line matching.
Both "In-Reply-To" and "References" headers reference Message IDs, which are unique email identifiers. Re:amaze uses these Message IDs to properly find and thread conversations.
The "Thread-Topic" header does not include any unique email identifiers, which is why its used as a last resort when sorting email threads. Additionally, the system will look for a matching subject line in Re:amaze. Archived and spam conversations are excluded in this type of matching. However, if an incoming email has a matching reply prefix (i.e. "Re:"), Re:amaze will re-open and thread the response in the corresponding archived conversation.
