Before I remove this from my todo list, I wanted to note that I attempted to contact the site for clarification on their recommended use. In recommending that messages be deferred, it isn't clear whether they mean that messages should be deferred until the listing is removed from their RBL (or what the lifetime of such records will be), or some other deferral strategy. I received no response to my query, so I'm deferring any effort to implement a module for this RBL. I'm not sure if the list is even being maintained. -- Mobile security can be enabling, not merely restricting. Employees who bring their own devices (BYOD) to work are irked by the imposition of MDM restrictions. Mobile Device Manager Plus allows you to control only the apps on BYO-devices by containerizing them, leaving personal data untouched! https://ad.doubleclick.net/ddm/clk/304595813;131938128;j ___ courier-users mailing list courier-users@lists.sourceforge.net Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users

Thank you. An RBL dependent one-time deferring mechanism would be fantastic.

He meant to defer a message on 127.0.0.2 reply *once* then accept it. I think your suggestion will be: "That is possible by developing a courier filter" because courier has to remember that one defer answer and accept the message the second time.
