" Local users do not have local accounts, "
Look at your routers and the transports they call.
- why would one of those ID's - by definition, with '..no local account'
be latched-on-to for local delivery at all?
- and if/as/when it is, *where* would Exim expect to deliver it?
NOT having 'local accounts' as in shell login, a /home/<usrname> dirtree, or
an mbox or maildir under /var/mail/<username> is fine.
But if the the only 'virtualization' you do is driven by /etc/[mail]/aliases.
you must either insure those addresees are NOT taken up by a local delivery
router/transport in the first instance, OR provide it with a place to drop 'em
or the privs to create such on-the-fly if you DO allow it.
'The aliases file' BTW does not have to be the *system* aliases file, either.
Sometimes easier to manage if it is of the same structure, but otherwise separate.
HTH,
