I would like to see an extension so that the MUA could contact the

points to the domains PubKey server.
How's this going to work when the MUA is:
- running on a host that's not connected to the 'net
- running on a host that can't connect to MX's (because
of local firewall rules)
- running on a host that can't connect to MX's (because
they're unreachable or down)
- running on a host that can't connect to MX's (because
they no longer exist)
- running on a host that can connect to the MX's but can't
get the user's public key because the user is no
longer valid
- and so on
There are way too many failure modes here that will render messages that
have already been received either temporarily or permanently unreadable.
