There's nothing there which indicates that Exim is doing any rejecting. To
test this, try 'exim -bh 211.72.XXX.YY' and go through a dummy SMTP
session.
Some thoughts:
Do you have any ACLs which are likely to be rejecting recipients from this
host? If so, you could use 'hosts = ! 211.72.XXX.YY' on the ACL to
whitelist them.
Are there any other log entries around the ones you've quoted which relate
to the same host? You could turn on heavier logging with log_selector =
+all.
It's possible that the remote host doesn't understand something about
Exim's ESMTP support, so try setting smtp_banner to something which
doesn't include the string 'ESMTP'
