Forwards and rules are in the mailbox directories(don't know about ver7 but
if not this will be oversome by having a SQL database. If the mailbox
directories are kept on a common store shared between the servers, they will
be no data loss. In other words all you are replicating is the registry
really - the actual Imail settings. If you use a shared store and Co-Standby
server below, it should work. If you are really interested in all the
possibilities you could try Microsft Clustering Services. Check out Magdy
Ibrahim from this list. He has offered to help with that implementation,
apparently he has it up and running.

Have you looked into Octopus? http://portal1.legato.com/products/octopus/

It will replicate your data and then do byte level transactions.

Legato Octopus FAQ
----------------------------------------------------------------------------

Q: Does Octopus replicate data?
A: No. After the initial synchronization, which does copy all of the source
files to the targeted server, Octopus keeps the source and target servers
synchronized by replicating file operations, not data. Some examples of file
operations are data write, truncate, rename, delete and permissions update.
This means that if the SQL server updates a 1.5G database by writing 300
bytes at a certain offset, that 300 byte WRITE command is performed on the
target just as it had been done on the source.

Is a Clustering solution. Not exactly sure how the mirroring is done on this
one. But if a fail is done, it assumes the identity down to the IP addresses
and all.

If  all  of  these requirements are met, you will be fine. How to meet
requirement (d) is up to you.  Sandy

In our quest for the perfect IMail, Craig's got us all very excited...so we
do listen to your very detailed advice Sandy, but you're not as much fun
: ). Craig, keep us dreamin, but I believe folks will loose some, perhaps
lots of data especially if (d) is not met, no?

James
