This bug was forwarded to both the author (Stephen R. van den Berg) and the last upstream maintainer (Philip Guenther).
We received a private reply from Philip Guenther, which is partially reproduced below (after asking him for permission), as it is of general interest: ---------- Forwarded message ---------- From: Philip Guenther [...] Unfortunately, I don't see procmail as a good base for mail filtering now. IMO, procmail brought two things to the table at the time: a more powerful--though obtuse--filtering language, and a better systems base for accepting and delivering messages. The language is a poor match for the complexity of modern systems with lots of MIME traffic, while the base is--IMHO--too complex, too clever, and written in a style that doesn't attract new maintainers. What were strengths in the past are no longer valuable and have become liabilities for a program exposed to general Internet email. I learned much from procmail and it filtered a lot of email for me and the places I worked at, but the world has changed and I moved on years ago. I recommend others do so as well.
