Looking more through recordio, I have notice that either remote host
(out of my ISP) or direct telnet against the qmail smtp server,
generate a HELO command that works ok, however the emails sent using
command line "mail" command from our webserver (within our ISP
network) generate a EHLO command (smtp Authentication I guess) why ?
How can I setup my qmail to override this behaviour ?
Thank you

I've logged on to remote host using ssh, then i have issue a "mail" commad
below the smtp log file with recordio :

@4000000045a64e7f2fc32664 tcpserver: end 17952 status 6
is the problem related to SMTP Auth ?
Thank you
