Seems fairly plain. The system you are obfuscating as "inbound server"
will not accept a sender address of just "root".
It's unclear if it's talking about the envelope From or the
headers From: - but in any case, you could check the configuration
and logs of that system.
And you could consider whether for this source of messages you
should have your Exim configured to use "submission mode",
so that bare names get qualified - because you need to act
as an MSA rather than an MTA. For these messages only.
