Fundamentally, everything works, except I am unable to send e-mail to one domain. My server is set up to handle Internet mail. DNS is used for mail resolution, not a Smart host. Messages delivered to the domain in question are delayed and eventually time out. Checking out the queues revealed that the remote host dropped the connection. The receiving domain's mail is hosted by mxmta.bell.ca. Does that mean I have to start the MTA service and configure an x.400 connector? Or is there some other parameter that I have to modify.
