I needed the "from" address, to pass as the -f option to sendmail. 
pm-lib.sourceforge.net contains a procmail snippet for determining the from
address without making an extra call to formail, so I used it.  (This makes
up the 13 lines or so of code that set OUTPUT.)  I just realized that pm-lib
is GPL'ed and Horde is LGPL'ed, so maybe it wasn't appropriate to do this;
if you'd like me to rework the patch or contact pm-lib's author for
permission, please let me know.  (Sorry, I'm not very familiar with the
process for including code snippets from one open source project in
another.)
