That site is using a Cisco PIX for a firewall which has "SMTP Fixup" set.
Essentially it is Cisco's broken attempt at protecting mail servers behind a
PIX by intercepting and rewriting the SMTP session on the fly. In practice
all it does is break stuff (like ESMTP for a start). If you have any pull
with the remote site, suggest to them that they turn this "feature" off on
their firewall. There are plenty of sites out there explaining all of the
ways it is bad for reliable mail delivery if they need examples.
