That seems a somewhat simplistic solution to me... What about plain courier deliveries, i.e. forwarding without maildrop? IMHO, there should be a generic framework for setting forwarding policies and establish criteria for determining the type of any forwarding rule. For example, newsletter exploders, anonymous mailboxes, changed email address, secondary mail servers, all result in different types of forwarding. The reasons why different policies are needed, originate from concerns such as determining the responsibility for forwarding spam, avoiding to disclose sensible information, coordinating mail filters, et cetera. Besides properly setting the Return-Path, a policy might need to mandate a specific outgoing IP, a smart relay, some kind of authorization token, or other features. Would it be worth to plan such a general solution for Courier? I mean, we all have various forwarding rules scattered here and there, and don't want to have to upgrade them one by one whenever a new antispam forwarding mode comes about. Would it be convenient/feasible/cool to plan something in advance? ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!
