This is a known bug in some versions of Procmail, where if a filter
program fails the first byte of the message may be lost.

Either upgrade your procmail, or get the fix-it-up recipe off the
website and put it at the end of your /etc/procmailrc:

 ...voice or no voice, the people can always be brought to the bidding
 of the leaders. That is easy. All you have to do is tell them they
 are being attacked and denounce the pacifists for lack of patriotism
 and exposing the country to danger. It works the same way in any
 country.
