#
# pushes new validrcptto.cdb file to mailhub servers using SSH
# expects slaves to have a forced command attached to this key, and that
# the command will know what to do with the data we're sending.
#
# 2006-02-15 jms1 - expanding to also push rcpthosts, morercpthosts.cdb,
#   and a customized version of smtproutes. see this web page for more
#   information: http://qmail.jms1.net/mailhub.shtml
#
# 2006-07-16 jms1 - fixed a typo (a missing "done" in the loops which 
#   actually push the files.) thanks to Lawrence Sheed for spotting the
#   typo.
#
# 2007-01-26 jms1 - adding auth.cdb to the mix
