The Question is:
How do I setup and configure an SMTP server on OpenVMS?
The Answer is :
TCP/IP Services for OpenVMS offers this, TCP/IP Services licenses
are often included with OpenVMS, and TCP/IP Services installation
and configuration documentation covers setting up IP and selecting
and setting up the many available applications such as SMTP server.
TCP/IP Services documentation is in the same area as the OpenVMS
documentation. Please see the OpenVMS FAQ for pointers.
Third-party TCP/IP stacks are also available.
