I'd use hosts_require_auth, because *IFF* I have some entry in
passwd.client I'd suppose that this host *needs* authentication.

With hosts_try_auth it can happen that auth failes for some reason (as
it did) and exim tries to deliver w/o auth, getting 5xx and returning
the message. For my feeling it's not what I'd expect. I'd expect
exim retrying with auth until it succeeds or the message expires.

Wife: fine
