The verify sending server email never arrives - to any address, external or internal. I know the domain can send emails as I have a rival AR on there, which works perfectly. I have set the crons and verified the path and php version is 5.6 I've tried activating the database directly and making it ACTIVE, but the campaigns say pending sending or processing 0% or sending 0% The crons history all seem to say success, today within the last minute to hour. Really stuck that everything is stuck. Any ideas?
