Problem should go away if you set up an account for *yourself*, add it to the
'wheel' group, login with that UID, and su or sudo only if/as/when you *must*
function as root.
Exim will then see your mail submission as coming from the login UID, not the
EUID of root, even if su'ed to root - and should onpass the mail.
Nothing to do with Exim, but 'the wise' do not generally permit root login in
multi-user mode OR over-the-wire at all - nor necessarily even a 'wheel' group UID.
Safer by far to login with a limited-privs UID, su as required, even if that
means two steps (self to a second wheel-group UID, then again su from
wheel-member to root).
