Why this patch

I wanted to use Charles Cazabon’s pymsgauth, but most of my message submissions don’t come from clients running directly on the mail server. This patch adds a Unix-filter analog of pymsgauth-mail, called pymsgauth-filter, designed to work with qmail-qfilter and acceptutils. Together, they extend pymsgauth to handle messages submitted over the network.

Without this patch

When sending a message to one of DJB’s lists, deal with qsecretary by hand. Or use a Mail User Agent that submits via sendmail(8), and have it run pymsgauth-mail instead.

With this patch

When sending a message to one of DJB’s lists, use a Mail User Agent that submits via SMTP or OFMIP, and arrange for the server to call pymsgauth-filter with the local privileges of the authenticated sender.

This is very easy to do if you use acceptutils for SMTP AUTH, and is documented there.
