+Subject: [PATCH] Apply opensuse upstream patch 004-ipv6-support
+
+Appears to be related to this:
+https://bugzilla.redhat.com/show_bug.cgi?id=198422
+
+-----
+Changes email socket connection code to use more IP version agnostic
+calls. It appears to only be used by the scan email option and
+originally comes from the RedHat IPv6 awareness program mentioned
+in the bug report.
+
+In practice, I'm not sure how practical the implementation for emailing
+scans in xsane is as it does not look to support encryption, pretty
+much a given in today's world.
