[Dovecot] RE: Lock problem - take 2

I deleted the index folder to fix a lock problem described on my previous post.

I still cannot access the folder. Now, I have a file in the maildir folder named dovecot-uidlist.lock that must be corrupt. How do I fix this? I can remove this particular maildir folder and there is no great loss. But I want to know how to fix it, in case this problem occurs on an important folder.

Thanks, Alex
