We have G3 iMac and a Macbook both with the same login name and

the iMac using Migration Assistant a few days ago when originally
setup. Since then there have been Mail operations on the iMac and
I want to make the Mail on the Macbook match. If I mirror the Mail
folder using Folders Synchroniser as I use for backups will it work
or will I wreck Mail on the Macbook?

Hi Severin,
If your Mail Account is a POP account, doesn't look as though you can.
If it's a IMAP it is possible.
From Apple Discussions:
<http://discussions.apple.com/thread.jspa?messageID=4374039�>
"Synchronization of local mail data between computers by means of a
file synchronization utility is a really bad idea if more than one
computer is allowed to access mail between synchronizations.
Mail uses a global Envelope Index file to keep track of every message
within the ~/Library/Mail/ folder. If this file is modified on both
computers between synchronizations, there is no way a file
synchronization utility can handle the situation properly.
Another more subtle and dangerous issue is that Mail may use
different *.emlx sequence numbers to name the same message on
different computers, or worse yet, the same sequence number to name
different messages. The only thing a file synchronization utility can
do about it is create duplicates of some messages while overwriting
(i.e. losing) others.
Mail data “synchronization” at the filesystem level can only be done
reliably if it’s a one-way operation, i.e. if the entire contents of
the Mail folder on one computer are overwritten by the entire
contents of the Mail folder on the other. You should think of the ~/
Library/Mail folder as if it was a monolithic entity.
BTW, this is not a Mail thing. Although the granularity may be
different, you would encounter similar issues with any other mail
client because there is no way you can avoid the same files being
modified differently on both computers if you use both between
synchronizations. The only reliable way to achieve mail
synchronization between computers is using an IMAP account and
storing mail on the server. "
Cheers,
Ronni
