Hello,

lets say a client connects and triggers several errors. For instance:

  EHLO asdf
  ....
  mail from: [email protected]
  250 2.1.0 Ok
  rcpt to: [email protected]
  504 5.5.2 <asdf>: Helo command rejected: need fully-qualified hostname

why did the "Helo command rejected" come not immediately after the wrong
EHLO ? Why did postfix wait until failed relay, to report ehlo?

And even worse, the client tries to relay mail, but no "relay access
denied" is being logged.

I am much more interested in "relay access denied", than non-FQDN ehlo.

Does postfix have some priorities which errors it logs preferentially?

thanks,
