From 717e3dcdc3e55d72c8e4a1948708c34170dbf926 Mon Sep 17 00:00:00 2001 From: Hannu Hartikainen Date: Fri, 2 Jul 2021 12:13:09 +0300 Subject: [PATCH] lib: consider all instances of Delivered-To header When using notmuch-reply and guessing the From: address from Delivered-To headers, I had the wrong address chosen today. This was because the messages from the notmuch list contain these headers in this order: Delivered-To: hannu.hartikainen@gmail.com ... Delivered-To: hannu@hrtk.in In my .notmuch-config I have the following configuration: primary_email=hannu@hrtk.in other_email=hannu.hartikainen@gmail.com;... Before this change, notmuch-reply would guess From: @gmail.com because that is the first Delivered-To header present. After the change, the primary address is chosen as I would expect. --- lib/message-file.c | 13 +++++++++---- notmuch-reply.c | 7 +++++-- test/T220-reply.sh | 1 - 3 files changed, 14 insertions(+), 7 deletions(-) diff --git a/lib/message-file.c b/lib/message-file.c index 647ccf3a..68f646a4 100644 --- a/lib/message-file.c +++ b/lib/message-file.c @@ -291,11 +291,16 @@ _notmuch_message_file_get_header (notmuch_message_file_t *message, if (value) return value; - if (strcasecmp (header, "received") == 0) { + if (strcasecmp (header, "received") == 0 || + strcasecmp (header, "delivered-to") == 0) { /* - * The Received: header is special.
