Set up issues

Set up issues

Hi, can anyone help get this up and running.  So Far:

can't verify DKIM (default or added selector)
can't set up a group (error message - try later)
can't set up a forwarder to an email with a different domain
Can't seem to get anything to work.

I'm leaving on a trip tomorrow and I need this working asap.  Welcome any assistance offered.

Thank you
Connie
