[Dovecot] 1.0.15 --> 1.2.11 --> got too little data

[Andre Hübner]

Hello,

did updates from 1.0.15 to 1.2.11 and is in most cases succesful.
Sometimes dovecot leaves errormessage in Log:

IMAP(username): FETCH [HEADER] for mailbox INBOX UID 5106 got too little 
data (copying): 516 vs 528

Until now only Inbox was effected and no other folders. I delete cachesfiles 
in ~mail/.imap to solve this but is there a way to do this automatical (self 
healing)?
Dovecot could recreate complete caches if there was a difference in 
calculation.

Thanks,
Andre
