 This seems a wrong assumption by qmail-scanner: the 'Received:' header from
the MX running the scanner is right below the qmail-scanner one.

 I believe it shouldn't detect anything at all: authentication or source
identification are not its purposes.

 well, I believe that a customer running its own mail server should take its
own responsabilities with respect to what is going out of its MX.  Also, say
you get SA 'fixed' with respect to this issue. What about  the other
spam-checking software available? How they behave with those messages? Are you
going to fix all the receivers in the world? I would rather try to fix the
sources...

SA could disregard receiveds with 'with qmail-scanned' in it. That would fix
the issue as longo as those headers don't convey any useful information. This
is a dangerouse hack, however, because there may be cases in which that line
does convey useful data: we can't exclude this a priori. So your suggestion
doesn't look too strong to me.

But this is me, after all. The fastest way to get something fixed in SA is to
write a patch for it
