Of course, I might.  

What happened, was I wanted to shut out those who used our mailserver
directly.  I called Psi and asked them if they could tell me what
IP-addresses their mailservers had.  I explained that I planned to
shut out most of their addresses, but that I would let their mailservers
through.  She wouldn't tell me, so I would either have to accept the
spam, or shut out all mailservers not registered.

However, I do receive the standard replies when I complain
about spam to abuse at psi.net, so they have at least one mailserver that
we do accept mail from, and that they use to send mail out.

What I said was that we didn't receive any mail from them in that specific
48 hours.
