You probably want to set it to just "dotlock". 2) The mbox_*_locks settings affect only when locking mbox. It doesn't affect index file locking, which is where the above strace hangs. So you should also set "lock_method = dotlock". In any case there's something wrong in your NFS setup's lockd. It just shouldn't be hanging there. As for looking at the index file contents, you could use "idxview" to look at dovecot.index and "logview" to look at dovecot.index.log files.
