+Subject: [PATCH] drop the six dependency
+
+six is a Python 2 compatibility shim and smpplib does not need it on
+Python 3: six.iteritems is dict.items, six.int2byte is bytes of a single
+value and six.b encodes as latin-1.
+
+Upstream-Status: Pending

+AI-Generated: Uses Claude Code (Claude Opus 5)
