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? -- Bowie ------------------------------------------------------------------------------ Want excitement?
