We've been having issue and going around in circles with Tech support with our client using mail6. We have used telnet to connect to the server and have seen delays of several minutes before getting a response. Some mail is getting through, other mail is not. The sender of the mail is not getting a bounce back. Our client has no way of knowing how much mail they are not receiving. You need to find the issue on this mail server ASAP. If you need further information, you can see details on ticket RWY-52629-131
