This looks like a cisco router/firewall/asa/whatever intercepting
smtp traffic and doing own 'fixups'. Switch it off.

Most irritating was a Cisco between our mail server and the internet that
removed STARTTLS from our server's SMTP greeting ... .
Back to the OP: If a Cisco terminates the connection, the receiving
sendmail would log EOM and the transmitting server would get the SMTP code
from Cisco. Insofar, it could fit.
