OK, I figured out what was happening, but not why. The download agent I was
using (getmail), added the following two lines to all of my messages:
Delivered-To: postmaster(_at_)pwork
Received: from pop.et.byu.edu (128.187.122.159) by pwork with POP3 for
<postmaster(_at_)pwork>; 10 Dec 2001 02:43:29 -0000
This was making procmail choke and die extremely ungracefully. I configured
getmail to not add those lines, and now it works. Thanks for your help!
I am running cygwin, and am trying to get procmail working. I know that
many others
are running procmail on cygwin. For starters, I am trying to use it to
filter an existing test mailbox that has two messages in it by running
$ cat testspool |procmail
