Subject: Re: [9front] upas/smtp -h $fqdn not used for HELO dialogue

hello,

smtp option “-h” is not for HELO host.

hostdomain is used for FROM address, which is used if the recipient is non-existent.
FROM address may be different from HELO host.
while HELO host is the system address of the smtp server.

look rfc2821 in detail
