	One more thing, when I said that the index has grown too much is 
because index directory for this mailbox folder is about 850MB, and the 
mailbox originally had about 3000 messages. This is the list of files in 
the index directory:

root at myotis51:/mail/indexes/vl/vlo/expunged/mailboxes/INBOX/MNCS# ls -lh
total 853M
-rw------- 1 vmail vmail 127M oct 24 11:16 dovecot.index
-rw------- 1 vmail vmail 127M oct 24 11:02 dovecot.index.backup
-rw------- 1 vmail vmail 186M oct 24 12:14 dovecot.index.cache
-rw------- 1 vmail vmail 180M oct 24 12:36 dovecot.index.log
-rw------- 1 vmail vmail 138M oct 24 11:02 dovecot.index.log.2
