Hey Guys,
Quick Question here on DKIM. I want to get it setup and running and plan on using Office 365 to do the signing etc with. However my question is this we have an edge MTA where all messages are sent from our office 365 tenant.
Near as i can guess, that shouldn't be a problem but i wanted to check with you guys first so see if you thought enabling DKIM on office 365 and then having outbound messages sent via en edge device (Proofpoint) would cause any Signature problems.
The proofpoint MTA does show as an extra hop.
Thanks,
Robert

Do you know of any Microsoft documentation whcih specific covers setting up DKIM (office 365) behind another MTA?
as long as proofpoint doesn't modify the body hash, subject etc or other signed portions of the messages then i don't see how it would be a problem.
I agree with you in principal that we should have Proofpoint do the signing as its the last hop but that isn't always possible.
Thanks,
Robert
