Can anyone familiar with below failed description highlighted with bold. We are doing IP warm up process for China, and one of the domain QQ.com has high failure rate with below description.
Inbound email bounce (rule 'Momen_Code70_TransientFailure' has matched this bounce).
The error is related to bounce code generated by enhanced MTA which is connected to your Campaign instance.
I urge you to raise a support ticket to understand more about why the enhanced MTA threw this bounce code.
PabloRosero this is for ACC, though the question is valid for ACS as well.
This for Campaign Classic or Standard?
Vipul Raghav for follow up.
