Re: [bitfolk] Hivemind - MITM email for delivery to multiple servers?

I've been tasked with finding a way for our directors emails to be delivered to two servers (somewhat simultaneously). They use their "work email addresses" as personal accounts, as well as business accounts (don't get me started), and they don't want to be reliant on connectivity to the corporate Exchange servers, so I've set up a Docker mail server on their home network, but getting their mail delivered to both that MTA and the Exchange servers is above my knowledge grade.
