Hmm. I just looked Exim's sources. Looks like it creates the file with
empty contents. Also Dovecot has pretty strict checks in its contents,
so probably isn't related to this.

Anyway, if the lock files do work properly (and I tested it today that
it works at least with me with Linux and NFS), then I can't really think
of anything else than some file caching issue.. Is it possible for you
to try this with all NFS caching disabled? I'm not exactly sure how
FreeBSD's NFS caching works though..
