This is simply not true. Gmail absolutely drops mail after accepting it
from my server. Worse, it appears to be completely random so most of
the time e-mail that Gmail accepts is delivered. My hunch is that
different servers in their mail pool are configured slightly differently
or their internal routing after delivery is wonky. I have RC installed
but only one client of mine actually uses it, so I don't think this is a
RC problem either.
Good luck with getting any support from Gmail. You get what you pay for
with a gmail account.
