Include a tool to verify my own SPF, PTR records
When setting up a new server, or migrating to a new machine, several things might be forgotten, or settings might get outdated due to other changes in domains / DNS entries.
Why not include a tool to automatically check my own (i.e. of the KC server I am running) DNS entries such as PTR, SPF etc. for correctness or plausibility (as far as possible)?
This could be either a button in the Admin Web Interface (Dashboard widget?), or it could optionally be done automatically upon server start (I think the cost of bandwidth for that is neglectable compared to the benefit). The report could be displayed in the Dashboard, or sent via email to the server admin (like the backup notifications).
