If you set mbox_read_locks=dotlock, it should get created whenever  
Dovecot is reading the mbox file. But it's created ONLY during those  
times. For example opening a mailbox whose index files are up-to-date  
doesn't cause dotlock to be created. And when the mbox is actually  
being read, the dotlock is deleted immediately after the IMAP command  
is finished.

Does openwebmail create longer existing locks?
