This is a horrible subject line. I've been trying to resolve a DDOS issue, and ignoring a lot of email.
Here I had been thinking this was a sex-spam, and I just got around to wondering why the spam system isn't working quite right and they kept coming in. :P
Not sure if this was suggested, but use SSD's. With a ton of mail combined with Maildir random reads/writes, SSD's are like night and day.

Very sorry about nasty subject ;) Btw is it worth the offload on i/o by having some Dovecot index or cache on an SSD ?
Lately I've separated the indexes onto another SSD-based volume, just to save read/writes, but I don't think it actually improved anything.

I'm going to try dm-cache and flashcache asap ..
