Yes, easy to do.

So you don't have any trusted hosts?

No problem, just use a ldap-lookup.

In general no problem, but what about bounces?
In general, you could use an acl like this
require message = Your senderaddress must be the same as your username
senders = : $authenticated_id
This should deny messages, not send either with an empty envelope from, or
when the evelope from does not match $authenticated_id (you can set this
when the user auhtenticates)

No problem, check the docs for the redirect-router carefully.

Yes, you can have them anywhere you want, as long as you can access the
"datastore" with exim.

No, looks like a normal exim project ;)
You'll need at exim4 to do some of the more extended things.
