+Subject: [PATCH 1/2] Fix #80710: imap_mail_compose() header injection
+
+Like `mail()` and `mb_send_mail()`, `imap_mail_compose()` must prevent
+header injection. For maximum backward compatibility, we still allow
+header folding for general headers, and still accept trailing line
+breaks for address lists.
+
