No, it just prints to stderr. I wouldn't call that bypassing since
stderr is a standard facility of avoiding piping mail somewhere where
you don't want it.

You can add 2>&1 to your bogofilter call to have stderr and stdout
captured.

Via bogofilter stdin, yes.

Please show the exact command line you've used (if it's file lines of
Perl, fine, show them).
