thanks, alexa.  these things happen, and i won't even demand a refund :)
sympathies for the pain.

< micro-management = off >

i really appreciate technical details.  there are still a few operators
left in the ietf community, and we try to learn from our oopsies.  a
deeper post mortem would even be welcome as many of us are also trying
to deal with dmarc hell.  you run a medium scale mail operation and any
lessons you share are appreciated.
