Your cross-posting to mozilla.support.seamonkey and
mozilla.dev.apps.seamonkey seems to prevent your messages appearing on
aioe's netscape.public.mozilla.seamonkey. You would reach more people
without the cross-posting.
If this appears on aioe, that could be considered the proof. Of course
if it does not, my theory is junk.
