Postfix address rewriting did not change between these releases. In fact, $myorigin processing has only changed once since 1.0, when "local" vs. "remote" rewriting contexts were introduced in Postfix 2.2 http://www.postfix.org/postconf.5.html#local_header_rewrite_clients You clearly also changed the application that injects email into Postfix. -- Viktor.
