We got a new business unit
Couple of weeks when we sent out test emails, things worked.
But when we want to test them again today test emails are not working, The emails are not bouncing and nothing in the Not Sent report and in Send logs.
The error we are getting is ExactTarget.OMM.UnverifiedFromEmailAddressException: From Email Address failed email address verification. and attempt to use fall back from email address failed. We have the domain verified aswell
What could have gone wrong?
