/ext/email/send : Reject due to policy restrictions

[Ednt]

i send emails with /ext/email/send and get them rejected.
The email have encoded UTF8 in from and Subject.
(There is no need for this, since they are complete ASCII compatible)

From: =?UTF-8?Q?abc@ednt.de?= <abc@ednt.de>
Sender: <abc@ednt.de>
To: test@ednt.de
Subject: =?UTF-8?Q?EspoCRM:=20Test=20Email?=

We think the fault is the missing Dquotes, correct is: From: "Sender name" <sender@example.com>

We can solve the issue by adding DQOUTES arround the alias part (tested with a small external code)
But we can not find where to change the ESPO source code.

This solves the issue:

From: "=?UTF-8?Q?abc@ednt.de?=" <abc@ednt.de>

We found it !

/web/vendor/laminas/laminas-mail/src/Header/AbstractAddressList.php

Line 215

$emails[] = sprintf('%s <%s>', $name, $email);

Needs to be

$emails[] = sprintf('"%s" <%s>', $name, $email);

It does not seem to me as a proper fix of the problem.
