Yes. It would be like if I started adding a faked received header to my spam (if I were a spammer) that always included a reference to your outbound IP addresses. Then a DNSBL, if it is parsing received headers for IPs beyond the one that connected to it, ends up blacklisting YOU, even though none of the mail in question came from your server. That is why DNSBLs shouldn't trust a mention of a source IP address that they themselves have not verified. It blacklists an unrelated party, is my point. Not only is it unfair, but it makes for pretty useless and sloppy spam fighting.
