+This can be used to change the default TTL attribute. Only change this if
+you know what you are doing. The syntax is either a numerical value
+denoting the TTL attribute, or two numerical values separated by column
+specifying a vendor attribute, i.e. <literal>vendorid:attribute</literal>.

+If a TTL attribute is present, the proxy will decrement the value and
+discard the message if zero. Normally the proxy does nothing if no TTL
+attribute is present. If you use the addTTL option with a value 1-255,
+the proxy will when forwarding a message with no TTL attribute, add one
+with the specified value. Note that this option can also be specified
+for a client/server. It will then override this setting when forwarding
+a message to that client/server.
