I have 2 domains setup in Mail In A Box, but I am unable to send mail to them using MailGun. any other provider seems fine .e hotmail.com
Error: “Sender address rejected: Domain not found”
Any ideas?
Cheers

perhaps you forgot to add their custom DNS?
yourdomain.com TXT v=spf1 include:mailgun.org ~all
