My initial tests for CLucene were that it would take 30% of mailbox size
(compared to 50% for Xapian). But this was before I actually implemented
it to Dovecot.. I haven't really looked at how large the indexes
actually are.

Looking at Lucene indexes now for all of Dovecot and Dovecot-cvs mailing
list archives, the indexes are 29.1% of the original mbox sizes.

Only if you're using filesystem quota.
