Maildir + delivery time indexing.

The only thing I found that sucks on cyrus is the BDB usage (or 
the internal skiplist implementation) for storing indexes.  If the 
indexes fry, it is a long slow recovery.  In the "sucks for me, maybe not 
for others" category is everything is owned by one uid, and it isn't the 
actual owner.  Which means, grep is not the user's friend.

As to speed, like I said, with 30,000 messages, it is fast.  I can open 
such a mailbox in under a second with pine.  Some mail clients insist on 
downloading the *entire* index for a mailbox instead of just the page of 
data they need, those don't notice it so much.  And, with server side 
indexing, imap body searches super fast.

The reason I left cyrus is the db.  I'm now running Dovecot, which is 
_another_ maildir implementation.  With indexes.  Except those can be 
built at delivery time, or .. as needed when the mailbox opens.  And 
recovery time is damn fast.  You can blow away the indexes and few people 
will notice.  It also stores mail in the user's dir, owned as the user. 
Major downside: tt lacks the server side indexed body search.  "mairix" 
helps _me_ for that problem (I can run a CLI and a new mail folder is 
created based on my search parameters; as a bonus it checks ALL my folders 
at once, and is fully indexed with bodies).  That won't help RC at all 
though.
