Header DATE field not returned when placed after MIME section

2 Jun 2018


      Hello,
I am using Dovecot 2.2.34p0 on OpenBSD 6.3 stable.
I am writting an application using the vmime (http://www.vmime.org)
library (x-ref issue: https://github.com/kisli/vmime/issues/199).
I noticed through testing over my own e-mail server that in some
situations the DATE field is not returned upon ENVELOPE or
HEADER.FIELDS request.
The e-mails at fault happen to have the DATE field at the very end of
the header, after the MIME section.
Example 1:
Delivered-To:
Received:
Return-Path:
Delivered-To:
DKIM-Signature:
From:
To:
Message-ID:
Subject:
MIME-Version: 1.0
Content-Type: text/html;charset=UTF-8
Content-Transfer-Encoding: 7bit
Date: Fri, 01 Jun 2018 17:44:44 -0400
Example 2:
Return-Path:
Delivered-To:
Received:
Delivered-To:
DKIM-Signature:
From:
Reply-To:
To:
Subject:
MIME-Version: 1.0
Content-Type: multipart/mixed;
boundary="----=_Part_338_1573405959.1527768044781"
X-Mailer: EMail_2.0

Thanks in advance for the insight,
