Is there a limit to the number of domains you can add to the server? I thought no but I have 4 and I have this message in my hosting panel:
Your Mailgun account has exceeded the number of domains allowed!
Make sure you have entered payment information into your Mailgun Control Panel:
https://mailgun.com/cp
which will allow you to create more than 5 domains. Clear This Message
So do I have to setup a paid account with Mailgun?
