Of course.  I've always made significant effort to keep mail off you.
It's bad news you're not shielded from so much noise.

This was in the one you replied to, when you said nothing needed to be
done:

  No, I have identified only additional bug in GIF support. This bug
  is now fixed in both RC and HEAD. Emacs still can crash with broken
  libungif and I think it is too much work to identify the problem in
  old version of libungif. I have asked libungif author to release new
  version with better version informations.

Fixing future versions of libungif won't help when building against
current libraries and is unnecessary with the autoconf test.  That,
and the similar jpeg test, didn't get installed for Emacs 21.2, so
people can still build a version using the default configuration which
crashes when they get sent a GIF file by mail.  (I reported the
problem against 21.1 to bug-gnu-emacs; it subsequently got diverted to
emacs-devel.)
