As Larry would write:
Known causes of the "Would send" and "If reported today,
reports would be sent to:" behaviors include:

1. Parsing a message you are parsing the same message in
another window, or shortly thereafter. For instance,
when using the cut and paste interface, a network
connection problem while the spam is being processed
will produce this problem. Another way this can
happen is if one follows the "Report Now" link on
one's personal SpamCop page and later follows the
link sent in the mail response sent by SpamCop.
Finish the reporting one way or the other, but not
both.

2. Not parsing a message until several hours after you
forwarded it to SpamCop.

3. Forwarded spam consisting of just headers and
no body text (No body provided, check format of
submission). To report, add some text like
"No body included." before forwarding. A slight
variation on this theme is mistakenly removing
the blank line that separates the headers from
the body. There has been at least one report
that the commercial product "SpamKiller" from
McAfee will eliminate that blank line if you view
the details of a piece of spam and copy/paste from
there. Ensure there is such a blank line when
forwarding to SpamCop (or pasting).

4. When using the cut and paste interface, a network
connection problem while the spam is being processed
will produce this problem. The cure is to back up to
the submitting page, verify the information is pasted
correctly, and try again.

5. Some bug of an unspecified nature. If you can reproduce it,
we would all like to know. (Some people have found that
trying again with the same piece of spam does not encounter
the problem again.)

Note that the display from SpamCop Tracking URLs will _always_ say
"Would send...", so it is important for the person encountering the
problem to know whether the "Would send..." occurred on the first viewing,
not just after the fact.
