We have been using the CDOSYS for 15+ years to send messages. The problem is they are getting kicked from gmail and others because gmail is looking for domain verification. If we are just sending to our own server they all work fine. But when sending to gmail and some others they get bounced.
Also, AS I understand it, If we use the API then the sent emails will end up in the sent items folder, yes ? This way we can more easily track what was sent and by who
