Invalid Message Id

[Fireside Admin]

I was testing the emails sent through your system using Mail-Tester.com and got the error: SMTP: Message-Id is not valid, according to RFC 2822

I wrapped the internetMessageId in “<” and “>” and the error went away.

The changes I made were to /post-smtp-extension-office365/inc/Engine.php

Line 79 went from:
`
$payload[‘Message’][‘internetMessageId’] = $message->getMessageId();
`
to
`
$payload[‘Message’][‘internetMessageId’] = “<” . $message->getMessageId() . “>”;
`

I hope it helps someone else.
