I think that the problem with that in this situation is that the -p switch
to rsync will set the permissions to the same UID/GID as what it on the
sending machine as a numeric value (89:89 normally). When the sending
machine receives the files it will set them to 89:89 but there will be no
corresponding group. I've done the exact same thing as you outline above
only you have to make sure that the UID/GID numeric values are the same (ie,
vpopmail=89 vchkpw=89) on both sides _before_ you do the file transfer.

If you do the transfer and _then_ set the values to match you will have to
"reset" the permissions as I've outlined above to make everything jive
again.
