I think it might probably be the same issue that had already been
described one year ago for 2.2.0:
http://thread.gmane.org/gmane.mail.imap.dovecot/71636
(Although in my case, the "Cached message size smaller than expected"
difference is always 1 byte.)

Too bad. Unfortunately it's not easy to switch for me. :-(
Is mbox really such an uncommon scenario with dovecot? AFAIK it's the
default config shipped with most linux distros..

Hmm - I think that's very unlikely a kernel issue. It's a Redhat EL 6
kernel so that kernel is actively maintained and very widely used.

Yes. I suppose. ;-)
However, I don't remember that reason now. :-) Maybe I read some
recommendation about that? Maybe about large mailboxes?
