are up ;-)) cause I don't know how mutch it cost to rebuild indexes
The index rebuilding itself doesn't take hardly any time at all. Also if old indexes exist, they aren't rebuilt but rather just updated.
The biggest potential performance hit with losing indexes is losing cache file. Clients which often request the same information from mailbox (eg. mail headers) are faster if the information is already available from Dovecot's cache file so it doesn't have to open each mail separately. Webmails especially do that.
