does anyone here have MTA-STS running with Sophos Central Email and can report their experience here?
Is this even possible or were there problems with the implementation?
Lukas Niewalda Thank you for posting in the Community. I have not seen much cases/queries about MTA-STS. However I found this https://community.sophos.com/sophos-email/f/discussions/132656/sophos-mta-relay-as-smarthost-desination this is about outbound emails though. Perhaps this might help you.
We do have official support for MTA-STS and ARC on our roadmap for 2023. I just don't have a solid timeline yet to share.
That are very good news, I am very glad to hear that.
