.... REJECT we reject you (#code)

where only you know what #code means.

but this is a really bad idea. when I get rejected without a reason I
can work on, I simply blocklist the other side. remember: this story is
about reputation. if you think you can solve your spam problem using
your own measures, don't forget that we too have a problem with spam.
and if you take a measure that might work for you but causes problems
for us, then we'll consider that you're part of the problem.
