Queue file ID is generated (for resubmitted/reconstructed mail) as a
dunction of the inode numer and the current millisecond. So you cannot
create the file on one filesystem and then copy it over to the
outgoing directory (which happen to be "incoming", usually;-), since
that would break that relationship (inode numbers are only unique in
the respective filesystems. Doing a copy would mean having possible
duplicates in the series)... So that mandates that the "moving into
place" need be through linking, or on other words an mv, not a copy
operation.

All that is mandated is that the work directory and the respective
outgoing directories be on the same filesystem... Not the hold,
IIRC;-)... Or you could try run multiple MSes.

But really... What kind of requirement would mandate you set it up
like that? Are you sure there is no other, more or less sane, wayto do
it?
