No, my system rejected the mail from the remote. The postmaster of the remote contacted me and gave me the bounce.
With the clarifying details in mind, I re-read your original message and it looks as if 157.230.63.40 is listed in dnsbl-3.uceprotect.net. Maybe that's part of the problem.
% dig 40.63.230.157.dnsbl-3.uceprotect.net
40.63.230.157.dnsbl-3.uceprotect.net. 1999 IN A 127.0.0.2
