DefaultHeaders plugin is encoding values

[coudenysj]

When I use the "long email notation" in the default headers, the headers in the email get encoded.

'default_headers' => array(
    'From' => 'Test <info@example.com>',
    'Reply-To' => 'Test <info@example.com>',
),

Gives me:

Date: Wed, 24 Sep 2014 09:30:04 +0200
From: =??Q?Test?= <info@example.com>
Reply-To: =??Q?Test?= <info@example.com>

The encoding is done in the Zend\Mail\Header\GenericHeader::toString() method.

Is there a way to avoid this?

Is it a problem?
This kind of encoding is valid (according to RFC: https://www.ietf.org/rfc/rfc2047.txt), and from what I checked, e-mail clients don't have problems interpreting it.

Outlook is the one to blame. Even the subject is malformed in Outlook.

From: =??Q?Test?= <info@example.com>
Reply-To: =??Q?Test?= <info@example.com>
To: =??Q?Jachim=20Coudenys?= <jachim@example.com>
Subject: =??Q?Subject=20encoding=20failed?=

I'll try to figure out how to fix this.

I added the MessageEncoding plugin without specifying 'message_encoding' => 'UTF-8'.

I removed the plugin and it is working as expected.
