Obviously, this isn't ideal. I'm surprised nobody else has been snagged by this before. I've been using Amanda on Cyrus mailboxes for years, with lots of recoveries. I guess I've just gotten lucky.
We have no experience with cyrus, yet, but have been talking about it for a while. After reading this I forwarded it to a co-worker, who wrote back this: Don't let cyrus do it.
From http://cyrusimap.web.cmu.edu/imapd/overview.html#singleinstance
-- Single Instance Store If a delivery attempt mentions several recipients (only possible if the MTA is speaking LMTP to lmtpd), the server attempts to store as few copies of a message as possible. It will store one copy of the message per partition, and create hard links for all other recipients of the message. Single instance store can be turned off by using the "singleinstancestore" flag -- Obviously this won't help the person with the failing restore, but it's something to consider for everyone else. Who really is short enough on disk space in this day and age that they think storing duplicate e-mail with hard links is still a good idea? (And just btw, we had lately been losing the battle against spam using spamassassin, even though it was pretty effective when first deployed. We recently added graylisting and are seeing very few spam making it through now.) -Mitch
