Custom-Headers

[informatJonas]

Hi,

could you implement the functionality that you can send custom headers with?

I have already implemented this on a test basis.
See here:

return array_filter([
	'subject'                => $email->getSubject(),
	'sender'                 => $this->toRecipientCollection([$from])[0],
	'from'                   => $this->toRecipientCollection([$from])[0],
	'replyTo'                => $this->toRecipientCollection($email->getReplyTo()),
	'toRecipients'           => $this->toRecipientCollection($this->getRecipients($email, $envelope)),
	'ccRecipients'           => $this->toRecipientCollection($email->getCc()),
	'bccRecipients'          => $this->toRecipientCollection($email->getBcc()),
	'importance'             => $priority === 3 ? 'Normal' : ($priority < 3 ? 'Low' : 'High'),
	'body'                   => [
		'contentType' => 'html',
		'content'     => $html,
	],
	'attachments'            => $attachments,
	'internetMessageHeaders' => [
		[
			'name'  => 'x-custom-api-message',
			'value' => 'yes',
		],
	],
]);

With the custom headers, like for me "x-custom-api-message", you can for example exclude the messages which have a certain header on the rule when generating signatures.
