  1. Hello, i'm testing KSMG. Seems a great product but as the topic, i can't relay to any external mailserver I want to accomplish a direct integration (Internet -> KSMG -> Mailserver -> Client) using the mailserver of my clients (more than one like gsuite, rackspace, custom, etc). Message remain in queue with the connection error Any hint to get this configuration working? Any help appreciated, best regards!
