FortiMail Cloud Deployment

Hello FortiFolks,

I recently starting reviewing the FortiMail documentation for an upcoming project, and today was informed that the solution is specifically FortiMail Cloud. Everything that I was going over was related to "traditional" VM/Physical FortiMail solution.

Does anyone have any experience with this particular solution?

Is there a deployment guide for it specifically?

Can I use this cloud solution to protect an on-prem mail server? or is it only to protect, lets say O365?

I was looking for some help from a deployment and architecture point of view, since Im not sure how this cloud solution will fit in the exiting network.

Any guidance here will be highly appreciated, thank you all.
