This does not reproduce. I take your example message and double the number of To: addresses by appending the header to itself, and nothing is truncated when I send the result from one Postfix over SMTP into another Postfix. You did not show the entire message header in the postcat output, but I suspect that you will see a content filter at 127.0.0.1. Wietse
