Actually, I don't think that's true of photo.rectify.

There is a facility for mailing errors to the user built into the
libgis error functions (G_warning/G_fatal_error), and that can be
disabled by setting GRASS_STDERR.

However, photo.rectify has its own version of this functionality, and
there doesn't appear to be an override. Unless you have a working
"mail" program (which implies a working local mail system), you can't
see the messages.

OTOH, I suppose that you could create a dummy "mail" script which just
appends its input to a log file.
