Thats just a corrupted index file. Try to backup the file /var/vmail/mydomain/xxxxxx/indexes/.Deleted/dovecot.index.cache and then delete it. dovecot should recreate it automatically.

Just do what till told you and it will be ok. It could be a result of a server crash but you might consider checking your harddrive using s.m.a.r.t.-tools. Backup your files in /var/vmail/ ( on mounted external storage just in case! ) to delete/reset all index files you could do something like find /var/vmail -name "dovecot.index.cache" -exec rm -f {} \; or just delete the files mentioned in your log manually. I'd also recommend checking consisty of your hard drives just in case. Also make sure proper permissions are set to your vmail folders ( group and user ownership is set to vmail in faulty directories )
