 If you want that the messages that you forward appear threaded to the original
-messages being forwarded, you can add these headers to your forwarding template
-(for instance, `forward_as_body`):
-
+message being forwarded, you can add the following header to your forwarding
+template (for instance, `forward_as_body`):
 ```
-In-Reply-To: {{.OriginalHeader "Message-Id"}}
 References: {{ if (not (eq (.OriginalHeader "References") ""))}}{{.OriginalHeader "References"}} {{end}}{{.OriginalHeader "Message-Id"}}
 ```
 
-Please note that, according to the RFC, `In-Reply-To` header should be used only
-for replies (although it seems a common practice to use it too for forwards).
-Also note that most likely the receiver won't have any of the mails referenced
-in these headers.
+Please note that the [RFC](https://www.rfc-editor.org/rfc/rfc5322#section-3.6.4)
+only recommends adding this header to replies (although some clients seem to
+add it to forwarded messages too). Also note that most likely the receiver won't
+have any of the mails referenced in these headers.
