I think one of the problems is how sendmail rewrites sender addresses for
uucp mail.  The uucpproto/uucpm configuration supplied with sendmail (and
I suspect many sites are using this configuration) causes the local sitename
to be prepended to the address in the From header line.  This works fine as
long as all intermediate sites do the same thing.  But, when the mail
passes through a non-sendmail site (like fortune), this rewriting does not
occur and funny addresses are formed.  And replies go awry.  (This rewriting
is in addition to the normal UNIX from line at the beginning of the message.
As far as I can tell, this path will still be correct.)

I have noticed this behavior in mail I have received via cbosgd and ihnp4,
both running sendmail.  We are in the process of bringing up sendmail at
fortune, and this issue is on my list of items to be resolved before we
actually cut over to it.  Is there any standard which addresses this?
