I created a test calendar event and I study the resulted mail.

All are "pass" except for
Code:
spf=softfail smtp.mailfrom=me@example.org
      smtp.helo=forward1-smtp.messagingengine.com;
Further,
Code:
Received-SPF: softfail 
    (example.org: Sender is not authorized by default to use 'me@example.org' in 'mfrom' identity, however domain is not currently prepared for false failures (mechanism '~all' matched))
    receiver=mx5.messagingengine.com;
    identity=mailfrom;
    envelope-from="me@example.org";
    helo=forward1-smtp.messagingengine.com;
    client-ip=66.111.4.223
Code:
X-Mailer: MessagingEngine.com Internal Interface
To: me@example.org
From: Me <me@example.org>
Subject: Reminder: Test starts now
Message-Id: <20190920121500.2BBF319C13B@mailuser.nyi.internal>
Here <me@example.org> denotes my main mail address.

Thank you for helping!

I asked the support, they escalated my ticket and thats all for the moment.
