I have implemented munge from for mlmmj. Some people disapprove
of munge from, but it works for the couple of mailing lists I
run (and has been doing since May 2017, rather longer ago than I

I don’t know the correct procedure for submitting this patch, so
would be grateful if someone would enlighten me.
