[Dovecot] Dovecot corrupted index cache

[David Halik]

A guess would be that this is likely due to the endianess of the 
multiple architectures that the index is being accessed with. We have 
the same issue here across i686/x86_64/sparc. I'm about to post to an 
older email thread about this as well.
