If you say so. procmail isn't a tutorial on system file locking and security - there's limits to how much its own man pages should need to explain things from the ground up - there's other manpages for that.

I'm using maildir formatted mailboxes herein lies the confusion, man
says you don't need lockfile.

What type of file is your ACTION line DELIVERING to?

Wha, wha, wha, it isn't delivering to a MAILDIR? You're delivering via a pipe to a program???

When running formail via a pipe, you're NOT delivering to a maildir -- you're piping to a program. Here, the need for locking is to protect the integrity of the file which formail is manipulating, which most assuredly is not maildir anything. It isn't even a mailbox.

:0 a: for that flag in the same recipe? I don't know the man is not
clear. It says I don't need it and so does Nancy's tutorial.

No. In fact, on that recipe, you wouldn't add locking of any sort because the ACTION is a braced construct, not delivery to a file, directory, or even program.
