A little more digging found preline in my default delivery instructions. I am using this to get the Delivered-To header.DEFAULTDELIVERY="| /usr/lib/courier/bin/preline /usr/lib/courier/bin/maildrop -w 90" This seems to be what is adding the From_ header. The header does not appear if I remove the preline call. Yes, I do realize that preline is expected to add a From_ header... However, this is not a recent change -- it has been in place for years. But the From_ headers only started appearing after I upgraded to 0.73.1. Older messages only show the Delivered-To and Return-Path headers. Was there a change in preline? Or perhaps maildrop was previously removing the unnecessary From_ header and is no longer doing so?
Right, that's it.maildrop never needed From_ headers, to deliver mail effectively. Its not clear where the preline came from, there was never any need for it, ant that really looks like some leftovers from procmail. Procmail needed preline, but maildrop never did.
Until about a year ago, maildrop completely ignored the From headers, so this did nothing. Simply remove preline from the delivery chain. It is not needed.

Search patterns must now be specified in the UTF-8 codeset exclusively. • To make room for the new MIME-aware maildrop, certain, and likely obsolete mail server interfaces (mail handed to maildrop with an mbox-style From_ line, or with leading spurious blank lines) are no longer directly supported; must use maildrop together with reformail. See the maildrop(1) man page for more information. • Update sqwebmail to write maildrop mail filters in UTF-8. It's unlikely that any existing sqwebmail-written mail filters will have any non-Latin search strings; but if they do, the rules will have to be rewritten.
