Since this is going to the Cosmo list, for Server based sharing there =20=

will be a need
to store the majority of information that makes up a MailStamp. I =20
have already
added the fields I believe are needed for server sharing. And I =20
filter out the ones I don't need for
peer to peer sharing.

I suspect the same information that is need to dump and reloading a =20
MailMessageRecord
will be required to share with Cosmo. The only info that would be =20
filtered out for Cosmo
sharing would be parentAccount, Bcc, and probably at least one other =20
field. Although
parentAccount and Bcc are the two that come to mind at the moment.


Hope that helps,
