One idea to add into the mix here that i just raised on the SPF list is that
people should consider the use of dynamic dns to configure LMAP type
proposals.
Large ISPs have large number of outgoing mail servers with essentially
random IP address configurations. These are further complicated by co-locs
etc.
Can we use dynamic dns to address the configuration issue? If so we can
simplify the core protocol.

Yes, I'll add that.
Something like this is needed:
"Email submitted to a secondary MX for relay to the primary MX MUST
somehow have the LMAP policy of the domain it claims to be
from queried
and applied." . If only the secondary receiving the email
will have
enough information, then this could be said more simply.
Should this be added to one of the LMAP draft documents?
I'll add it to the discussion draft.
I just thought of another possible problem with LMAP. If a spammer
using direct-to-MX spamware sends email to me, from me, (as
I'd bet they
regularly do) it may not be caught by LMAP.
That's a local configuration issue.
