The only other explanation I can think of is some sort of firewall
between the client and your server messing with the protocol. Cisco
PIX are notorious for that, but IIRC the munge the banner so ESMTP is
not seen to be advertised. Have you tested a non-PTR-IP from the
server via "exim -bh ip.ad.re.ss"?

If that's not it, I'm stumped.
