+Subject: [PATCH] Reduce subscription confirmation address length to fit RFC
+ 5321
+
+The local part of mailing list subscription confirmation addresses
+formed of:
+
+  mailing-list-name "+confsub-" 16-random-hex "-" sender-address
+
+can get very long, especially if sender-address is long.
+However, RFC limits it at 64 characters.
