The "In-Reply-To" is still missing in your mails, so you're invariably
breaking threading.  T'would be nice if you could make your mailer
behave :)

This... doesn't look like an ACL created by Cygwin.  If you're running
Cygwin 2.4.1, the acl should always at least contain ACEs for the
default POSIX perms, plus a NULL ACE:

foo NULL SID:(DENY)(Rc,S)
    VINSCHEN\corinna:(R,W,D,WDAC,WO)
    VINSCHEN\vinschen:(R)
    Everyone:(Rc,S,RA)

For directories also inheritable default perms for "CREATOR OWNER" and
"CREATOR GROUP".  Is that really a Cygwin mkdir?!?  And then, what about
this unknwon group with gid 213?  What does

  $ getent group 213

print?  Something's weird here...


Thanks,
Corinna
