[Dovecot] Corrupted index cache file

[Maarten Bezemer]

For what it's worth..

I've seen the FETCH error with "got too little data" also with Maildir 
setup. So, not only limited to mbox.
This was quite some time ago with (I think) 1.0.15. Back then, I just 
removed the dovecot.index and cache files (leaving only the uidlist file) 
for that maildir folder. Worked fine after that (except I had to convince 
Outlook to resync.. Mail bodies in Outlook cache sometimes didn't match 
with mail headers...)
Currently running 1.2.15, no further corruption seen.
