PIX firewall ??

PIX firewalls don't know how to properly speak (e)smtp, and this causes
errors. Best way to fix this is on the PIX itself (make sure you have
the latest patches etc. and consider disabling the smtp fixup mode), but
as a workaround you could disable esmtp on the postfix box, by having
this in main.cf:
smtp_always_send_ehlo = no
smtp_never_send_ehlo = yes

Tot ziens,
