I don't trust procmail anymore after CVE-2017-16844. It took me a long time, I had a weak spot for it, you might say, despite its horrible looking source. But now it's over. I have rewritten my delivery framework using Perl and Mail::Audit, and I feel very relieved. > I highly recommend using it.

It would take a huge .msgid file to detect that, and remember formail does a linear search through it. I'm experimenting with using the filesystem as a hashtable, creating an empty file based on each Message-ID header (of course I munge it to get a valid filename). -- Please don't Cc: me privately on mailing lists and Usenet, if you also post the followup to the list or newsgroup.
