Exchange Web Services (EWS) as mail type

Hello together,

I am currently facing the problem with a project that I cannot use the SMTP protocol for sending mail.
I didn’t find anything for it in the docs, but is it possible to send via EWS? GitHub - jamesiarmes/php-ews: PHP Exchange Web Services

Or alternatively extend the standard mailer with this function?

You can use different transport settings, like external mail services, maybe this also works with such a library, but I can’t really tell.

Yes, that’s what I was thinking. I also found out that Kirby uses the PHPMailer in the core. It seems that it can’t do that. At least I have found nothing in the documentation about it… I try it further
