Perhaps it might work for some situations, but it would need code to:

  - locate the log file (difficult if you're logging to syslog)
  - parse the log file
  - figure out if crash was caused by a broken index file or something  
else

All of this just to work around some rare bugs that shouldn't be  
happening in the first place. And in some situations it might delete  
index files that didn't even need to be deleted.

Of course you could write all of that yourself to a script that's  
tailing Dovecot's error log and it would work just as well as anything  
Dovecot could internally implement.
