Install ethereal, snoop your network on port 25, and use the
"follow TCP stream" feature of ethereal to save the outgoing
mail to disk.

It won't supply you with mbox-ready files (there are other snooping
tools that do that, though), but in a way, this is better...

If you have a decent ISP, you can ask them for the logs corresponding
to a certain message-id, or transaction-id (usually mail servers give
you the transaction ID when the mail is accepted). Your sendmail log
should include that.
