Is it possible to setup stalwart to forward incoming email to another mail server?

[DavyLandman]

I want to have my email from my own domain forwarded to a payed host (posteo) so that I can avoid having a lockin.

Since stalwart also implements ARC, I was looking into this, but it doesn't look like it's currently possible to route incoming mail to a external mail address?

ARC is a protocol that validates an authenticated message chain, it does not have any effect on message routing.
It is possible to route messages based on rules, please refer to the routing section.

as I understood it, if you forward an email to another server, the SPF & DMARC headers tend to fail, and ARC is a way to still say: hey, it's fine, me the forwarder checked it all?

Sorry if I mis interpreted it. I'll take a look at the routing section, thanks. I somehow assumed it was for outgoing mail, like smtp proxying.
