1) http://www.exim.org/eximwiki/DontObfuscate

2) Submission mode defaults to treating the authentication ID as an 
_unqualified_ localpart. If your authentication IDs will always be a 
fully qualified user address, then you want to use:

control = submission/domain=

Note that that only applies to _authenticated_ email, not to 
unauthenticated relayed email. If you don't intend to support 
unauthenticated relayed email from any hosts, you should remove "accept 
  hosts = +relay_from_hosts" from your ACL entirely.
