Re: Using SUBMIT without bothering the user (was Re: MyDoom, Sorbig - Actions taken?)

As John pointed out, draft-hall-email-srv-00.txt uses the domain in the
email address as the principle key for these lookups. In answer to the
point you raised, the address bindings are per-identity, not global.
'Normal' users typically have MUAs where each email address is bound to a
different identity profile, which may use different submission and/or
retrieval servers. Also, the draft specifically states that these lookups are intended to be the starting point, not the end of the process. Folks can use it to bootstrap a configuration process, can use it to perform a
relatively complete configuration process, or can skip it if they want.
The spec tries to standardize an algorithm and the necessary elements so
that different MUAs do it consistently, not to enforce a procedure.

One other point is that the draft also defines a retrieval algorithm and
SRV mechanism, and is not limited to submissions.

Mumble. configuration is a Hard Problem. With very few exceptions most of the solutions I've seen to do configuration end up making the situation more complex, less fault-tolerant, and harder to configure correctly - and it's usually because they key off of the wrong thing for the particular quantity they're trying to configure. For example, DHCP is really only good for things that are inherently tied to the network location, which isn't much besides address, netmask, and default route. (and it botches address configuration by making IP addresses ephemeral).
