Re: [Lilux-help] Port 587 the solution?

There is an IETF working group which aim is to work on those issues. As mailing-lists are opened to anybody, you can follow their progress or even give suggestions. More info on http://ietf.org/html.charters/marid-charter.html Description of Working Group: It would be useful for those maintaining domains and networks to be able to specify that individual hosts or nodes are authorized to act as MTAs for messages sent from those domains or networks. This working group will develop a DNS-based mechanism for storing and distributing information associated with that authorization. The primary current use case for this facility is to allow recipient MTAs to confirm that peer MTAs' actions are authorized by specific domains or networks. This will help combat a certain class of domain forgery common in spam. The solution chosen, however, should be generally useful for others which might check this authorization data.
