I don't think it can be accomplished without a massive and fundamental =

change to courier. On a unix fs, a hard link is just a reference to the =
=

destination file. The link points to an inode which contains permission =
=

data, etc. Either the first user to receive the message would have =

permission to modify it, or no one would. The latter would require that =
=

the entire system drop the unix security model and start storing =

messages either in a central location, or in a DB like Exchange. =

Maildrop would likely have to be removed from the system, as well.

It's really not worth being concerned over until you have as many users =

as google, and a lot of duplicate messages sent to the bulk of them.
