Hi Wietse,

The "help" command didn't generate a notification, so I tried a
variation:

    $ telnet giardia.yourweb.com.au smtp
    Trying 61.8.3.32...
    Connected to giardia.yourweb.com.au.
    Escape character is '^]'.
    220 giardia.yourweb.com.au ESMTP Postfix
    helo dude
    250 giardia.yourweb.com.au
    mail from:bugaphid.net
    501 Bad address syntax
    mail from:<bugaphid.net>
    250 Ok
    rcpt to:<billnothere.org>
    554 <billnothere.org>: Relay access denied
    quit
    221 Bye
    Connection closed by foreign host.

Notification sent to postmaster:

    Transcript of session follows.

     In: helo dude
     In: mail from:bugaphid.net
     In: mail from:<bugaphid.net>
     In: rcpt to:<billnothere.org>
     In: quit

    No message was collected successfully.

As I said, this is on RH 6.1 with Simon Mudd's postfix-19991231_pl07-1 RPM.

Stock RedHat kernel (shame!) version 2.2.12-20.
