You're missing the central point. "They" are _not_ getting any "relay
through".
They're connecting to your SMTP port and sending you a message,
addressed to [EMAIL PROTECTED], from envelope sender
[EMAIL PROTECTED] qmail-smtpd accepts and queues the
message, and the SMTP transaction is completed. They disconnect.
qmail-send sees this message in the queue, tries to deliver it, and
realizes that there's no such user on your system. qmail-send composes
a bounce message to [EMAIL PROTECTED], with a null envelope
sender, and a From: header of "Mailer-Daemon" or some such. However,
when trying to deliver this message, otherdomain.tld is saying (during
the initial SMTP transaction) "no such user", refusing the message.
qmail-send is then seding this to you, telling you that the bounce
bounced.
Where in all this do you see any relaying happening?
