[gmime-devel] Mail header change of g_mime_object_append_header()

[デージーネット 大野 公善 <ohno designet co jp>]

Hi,

I will use g_mime_object_append_header() in my application.

When I use g_mime_object_append_header(), it was changed the original
mail header (To, From).

For example,

[Original mail]
Date: Wed, 11 Nov 2015 07:46:49 +0900
From: =?ISO-2022-JP?B?GyRCQmdMbhsoQg==?= <ohno int example jp>
To: =?ISO-2022-JP?B?GyRCMDhAaCROP00bKEI=?= <ohno out example jp>
Subject: =?ISO-2022-JP?B?GyRCJUYlOSVIJWEhPCVrGyhC?=
  :

[Changed mail]
Date: Wed, 11 Nov 2015 07:46:49 +0900
From: =?iso-2022-jp?q?=1B=24BBgLn=1B=28B?= <ohno int example jp>
To: =?iso-2022-jp?q?=1B=24B08=40h=24N=3FM=1B=28B?= <ohno out example jp>
Subject: =?iso-2022-jp?B?GyRCJUYlOSVIJWEhPCVrGyhC?=
X-SaMMA-Enc: YES        <- Appended.
  :

Mail header(From and To) is changed to Quoted-printable from Base64.


I want to prevent this change.
Is there a way to prevent?


I use GMime 2.6.20.
It occurred in g_mime_object_append_header() of gmime-2.2.11 and later .

Regards,
