I didn't let it through. The original email sent
by the person was
rejected from the mailing list. If you received it, it means the
person emailed it directly to you in addition to mailing it to the
mailing list address. Notice that this thread was started by someone
*replying* to the email, not the original email itself.
The first email I see on this thread was Michael Smith replying to
you, and it looks like it was sent just to the mailing list.
