Is "apache" a trusted user? If not, the first two bounces are exactly
what I would expect from a process running as "apache" that submitted
the bad message, because an untrusted caller cannot set a sender.

The third bounce is mysterious. The mystery is that the headers quoted
in the copy of the message do not contain the Received: header that Exim
adds to all messages.

I don't understand this at all. Does it show up on the Exim log? Without
a Received: header, there's no record of the Exim message-id which could
be used to identify it.
