Everything in this directory (except this file) has been contributed.
We will not fix bugs in these programs.  Contact the original author
for assistance.

Some of these are patches to sendmail itself.  You may need to take
care -- some of the patches may be out of date with the latest release
of sendmail.  Also, the previous comment applies -- patches belong to
the original author, not to me.
