I've got my proxmox set up for somet 40 domains going to our own mailservers.
One client for valid reasons need to have their emails delivered to an external server.
a) How can we still do dkim signing for them?
b) Would it be possible to add their dkim signature on our proxmox server? (i would guess no, as there's only 1 setting for it)
c) Would it be better that they do not sign their emails in their server, and delivers via our proxmox, and we set MX as our proxmox also and handle the whole DKIM with our key?
