So the MX record is updated. Now I just need to wait 4 hours for the changes to propagate (the TTL was set to 14400 prior to this).

Then (finally, hooray!) I can update the A record for the domain.

@GeorgeEdison thanks for the bugs, the restart button will be easy, but permissions shouldn't be an issue as we're running in daemon mode but I'll look in to it

@MarcoCeppi Thanks! The site is live now.

@GeorgeEdison yeah I saw your announcement!
