it's been a while since i've swam in the murky smtp waters - but if memory serves the errors you're seeing are related to DNS misconfiguration of some sort - either you don't have RDNS set up right or your box isn't an MX record? - i admit it's been a while though

$ host 66.179.61.137
Host 137.61.179.66.in-addr.arpa not found: 2(SERVFAIL)

the other mail server may have something like
Code:
smtpd_recipient_restrictions =
    ...
    reject_unknown_client,
    ....

so, fix your DNS.
