Note also that there are privacy issues involved in having a UUID

if we do this for sharing purposes, it should be a different and
*secure* UUID (i.e., one not generated using the Ethernet hardware
address) for each effective sharing conduit, to minimize the amount
of trackable information being distributed about the person's machine.

+1 the UUID would just be a random id and have no ties to the users
hardware or software.

Not only that, but it would have to be a *different* UUID for each email account, or the user's identity can be compromised. For example, if I use an email account with a phony name or "handle" for one set of purposes, and another account with my real name, for work/business purposes, my identity is compromised if Chandler uses the same UUID on both sets of email. Somebody who has seen an email from *either* account can potentially Google the UUID to find what other email accounts have used the same Chandler client! This would be a serious failure to protect user privacy.


Yes good point. I think I might go with the message id caching strategy instead. I need to think about this some more.

Thanks,
Brian
