[Discuss] DNS issues with Blu server

[Jerry Feldman]

Since we moved the server we have had some intermittent errors mainly at
our host.

But, more importantly email to Gmail accounts has had SPF and DKIM issues:

we do have SPF and DKIM setup in our zone files. If anyone can help me with
this, I would appreciate it.
