In following-up my previous question, I am trying to use munpack in an automated fashion.

I'm trying to do this with procmail.

> cat .procmailrc
    | sleep 5 ; munpack /var/spool/mail/testmail ; sleep 5

However, this doesn't do what I expect it to - it's just deleting the message (the /dev/null line), and appears to not be running the script line.

What am I missing?

Got it! need to just pipe the email into munpack on its own, which effectively causes the issue to /dev/null.

> cat .procmailrc
    | munpack
