I am not aware of any "transparency" issues in either of those releases. You don't need to upgrade. There was once an undesirable interaction between "transparency" and 8-bit to 7-bit conversion, but that was in Postfix 2.0 snapshot (at the time called 1.1.N-YYYYMMDD) releases.

A tcpdump capturing the SMTP traffic from EBAY should show the lack of propper "dot-stuffing" in their sending engine. If they do it correctly, perhaps you have content filters or down-stream SMTP senders that are broken. What software other than Postfix do the messages traverse before forwarding? -- Viktor.
