Hi,

the following SMTP sessions works:

----------------------------------------------
telnet localhost 25
...
EHLO localhost
...
MAIL FROM: root
250 2.1.0 Ok
RCPT TO: root
250 2.1.5 Ok
DATA 354 End data with <CR><LF>.<CR><LF>
To: root
From: root
Subject: test

.
250 2.0.0 Ok: queued as 1FE944A4078
----------------------------------------------

I receive the email in the correct mailbox. My main.cf contains

  append_at_myorigin = yes
  append_dot_mydomain = yes
local_header_rewrite_clients =
In the received mail the From: and To: headers are indeed only
"root" (and not "[EMAIL PROTECTED]").

But what makes postfix accept the non-fully-qualified envelope sender and recipient addresses?

postfix is also used as a submission MTA. to reject non fqdn addresses, use the appropriate smtpd checks.

I don't want to allow this,
I want to enforce "MAIL FROM: [EMAIL PROTECTED]" etc...

This is invalid syntax. take a look at rfc[2]821.
