+Subject: [PATCH 1/4] outof: Introduce expandaddr flag
+
+Document that address expansion is disabled unless the expandaddr
+binary option is set.
+
+This has been assigned CVE-2014-7844 for BSD mailx, but it is not
+a vulnerability in Heirloom mailx because this feature was documented.
+
+This patch is taken from
+ftp://ftp.debian.org/debian/pool/main/h/heirloom-mailx/heirloom-mailx_12.5-5.debian.tar.xz
