Okay, by testing with swaks I've confirmed the suspicion that I broached in my previous mail: on the problematic system, the rewrite of the email header 'From: root' is to 'From: <aaaaa...@zoho.com> (root)', which causes the mail to be rejected by Zoho's server with '553 Relaying disallowed as @'. On the working systems, the rewrite is to a more normal 'From: root <aaaaa...@zoho.com>', which Zoho accepts. So: is this a bug? Is there some way I can get Postfix 3.1.8 to do the rewriting the normal way, like 3.3.2 does, or do I just need to upgrade Postfix? Celejar
