[ Robust/neat idea to support sender dependent transport selection. ]
sender_dependent_default_transport_maps (default: empty)
A sender-dependent override for the global default_transport parameter
setting. The tables are searched by the envelope sender address and
@domain. A lookup result of DUNNO terminates the search without over-
riding the global default_transport parameter setting. This informa-
tion is overruled with the transport(5) table.
Is "DUNNO" the right choice here? This is not an access(5) table, and
"DUNNO" may muddy the user's understanding or expectations? If we really
want to allow one to make exceptions for specific users or sub-domains
without explicitly specifying the default transport, I think that:
except.example.com DEFAULT
example.com transport:nexthop
No, adding a new magic result is not the solution.
or perhaps
except.example.com :
example.com transport:nexthop
is even intuitive, with the latter choice matching similar behaviour
in transport(5).
I like this. +1 for ":"
