Thanks. Noted.
I have a had couple of emails pass through my exim server whose logs
from the ARC verification logwrite report,
ARC_state: <fail> condition = true logwrite = reason: <AMS body hash miscompare>
I don't have access to the emails in question to examine their headers but
I am assuming that, in contrast with all the others, they were ARC signed
and that my ARC configuration is in fact working and doing the correct
thing, and that the only problem is the verification failure caused by the
upstream MTA's header/body manipulation. Does this look correct?
Thanks
Tom.
