Maybe something's spam-filtering it on the way to you, and I believe the
default list settings are to not send copies to e-mail addresses already
in a "to" or "cc" field.  Sometimes when I do "reply all" on a mailing
list, one of the e-mail addresses I'm replying to replies that the
message was not deliverable, or was considered spam, or whatever; and I
know there also exist spam-filters that aren't nice enough to tell the
sender.
