There is probably an anecdote from the Bell Labs from the early 1970s which either solves your problem or improves your understanding of it.

If SENDER is an acceptable envelope sender, just replace ${env+-f "$env"} with -f "$SENDER" and you're done (modulo the syntax error changes which will have to be undone, of course).

You cannot have two actions, so the double exclamation marks in your edited recipe are a syntax error. If there isn't a Return-Path: header in the incoming message, then of course, you cannot extract it, so the error is never reached anyway.

Using a global lock file with LOCKFILE=.procmaillock serves no useful purpose here, as far as I can discern. Running multiple Procmail instances should be safe unless (for example) you have replaced your real Sendmail with a hack of your own which tries to save something to a database with exclusive write access or something like that.

comment prevent procmail from adding Return-path
Check that the whitespace in [ ] and [^ ] is a space and a tab. Copy/pasting from a web page might not work correctly, as indicated already in the original answer.

No match could mean either that there is no Return-Path: header, or that you mistyped the regex somehow.

comment Understanding ulimit -u
For launching /bin/echo in a subshell? Really? Anyway, the original problem report was definitely from a server which doesn't have X11.

This does not explain why Bash will not run a single process when you set the corresponding ulimit to something like 50.

comment How do you use apt-get to only install critical security updates on ubuntu?
Perhaps I'm stating the obvious, but if you are running a stable distribution, the only updates you get will be critical updates (mostly security, occasionally fixing crucial breakage in a package).

The problem is not the extraction, but the handling of multiple matches. For a single match, grab it with * ^Subject:.*\/60[0-9]+ and you will have the number in $MATCH.
