Does procmail default lock the local delivery mail file as I have

In case of files, yes.
Just to be sure, you are talking about the mbox mail file. Your last
comment seems to assure me that you mean writing to an mbox file.
Procmail has by default locking support for writing to any file as
long as it is (at least) a regular file, that includes mbox and
maildir, of course.
Se also https://linux.die.net/man/5/procmailrc
which mentions using lock files.
I am piping the output of a formail command into procmail. No
receipts.
Piping formail also doesn't change the fact that procmail has its
default locking when delivering to files. But I did not get your
remark about receipts.
I am not using receipts where I see the use of lockfile in the
examples. I have a 'simple' formail command that is then piped into
procmail.
My procmailrc(5) does not mention "receipt". Maybe you mean "recipe"?
But then, almost everything in procmailrc is a recipe :)
ARGH!!! Mr. Malaprop strikes again. Rudd has nothing over me in using
the wrong word.
Yes, at some point it would be nice to work out how recipes work,
outside of the kitchen. But for now I am doing this all in the command
line.
