Is the Folder accessed by dovecod via NFS?

If that is the case, this bug might be caused by the NFS client caching 
filesystem metadata.

For example, if dovecot thinks it is opening a 1200 byte file (by 
believing stat(2) to give correct info), while the file on the NFS 
server actually is 1800 bytes, strange things might happen, depending 
on how the different info from stat(2) and actually reading from the 
file is used / handled.

It might help adjusting the mount options (actimeo?).
