I think it sends a 4xx error back to the sender, which means they
will queue it for resend at their end. I haven't tested this though.

I installed qsmtpd last weekend to give it a try.
I opted to install it on a different machine and used the queue/
smtp-forward
plugin to get it into the 'production' machine.
I changed the MX records of some domain names which receive a lot
of spam to
the machine running qsmtpd.
My question:
What happens when 'queue/smtp-forward' wants to forward the email
and the
'production' machine is temporarily (lets say 2 hours) unavailable. ?
Does queue/smtpd-forward implement some kind of waiting queue in this
scenario? Or will the mail be lost?
I am very impressed with qsmtpd.
It is currently blocking about 99% of our prior spam. Almost
entirely using
the early-talker en dnsbl (spamhaus).
It's by far the easiest to implement smtp server with spam blocking
at smtp
level.
