Yes, I'll probably change my first_valid_uid to a higher number.  Currently vmail is 399 since I've been running Linux for ages. 
  Thankfully there is 'find'.  Gotta change the MySQL table too.

I really do appreciate Dovecot and all the work that goes into it.  That being said, I don't think 'search' should create any 
files or directories.  I just wanted to see how much trash is on the system.  If you wanted to check 'CorpNews' which a few 
users have, after running 'search' now everyone has it.

The man page doesn't mention that 'search' updates anything.

I provide this feedback because Dovecot is great software and want it to continue to be.

BTW, now I have:
