I started using this wonderful tools just a few days ago. I am running version 3.5.4 on a linux server and already sent out my first campaign. This worked pretty well except for one address that is a .global domain. I confirmed this address is working fine, and I also checked the tlds-alpha-by-domain.txt file - the global domain is in there.
Am I doing anything wrong? Is there another place to check for allowed domains?
Many thanks for your quick help & regards,
