One might even reuse something like AOX for this.
SQL indexes aren't very helpful for IMAP-like data. It would be fun to some day have SQL backend in Dovecot (there already is read-only INBOX-only SQL backend), but I don't expect it to have very good performance.
I see... well I haven't tested AOX or dbmail so far (especially as they're not in Debian and I was too lazy till now to compile them)...
At least I had the impression that performance (especially in searches) was one of the major things these people were proud of.
I'll stay tuned, whether we ever see a fully usable SQL backend for Dovecot :)
