[Dovecot] maildirsize corruption

[Frank Doege]

It seems that iam using exactly nfs.

I use a postfix to put the mails on an nfs server where dovecot directly runs on.

Maybe it is related to the problem. I try it with this fix and report.

Thanks,

Frank

Looks like it handled those NUL bytes worse than I thought. Fixed:
