what's the downside? some legitimate mail will be delivered more
slowly; anything else? would any mail never be delivered? or would
that only happen in cases where a legitimate sender for some reason
never tried again, or got through again?

assuming there are no big problems with it i'm fine with it. i get
a lot of my mail through my school account, filtered to a gmail account,
and a bit more straight to gmail. i still get legitimate mail at ellipsis
but i get so much spam not caught by bogofilter or whatever we're using
that i usually spend a lot more time deleting missed spam than reading
the little real mail i get.
