> What is the proper method to create a module using install-ns.sh?

See the instructions on the wiki page or in the README file on GitHub. When calling "bash install-ns.sh" without further arguments, you get the listing of configuration variables in the first column of the SETTINGS section. E.g.

$ bash install-ns.sh
...
SETTINGS   build_dir              (Build directory)                 /usr/local/src
           ns_install_dir         (Installation directory)          /usr/local/ns
           version_ns             (Version of NaviServer)           4.99.31
           git_branch_ns          (Branch for git checkout of ns)   main
           version_modules        (Version of NaviServer Modules)   4.99.31
           version_tcllib         (Version of Tcllib)               1.20
           version_thread         (Version Tcl thread library)      
           version_xotcl          (Version of NSF/NX/XOTcl)         2.4.0
           version_tcl            (Version of Tcl)                  8.6.16
           version_tdom           (Version of tDOM)                 0.9.5
           ns_user                (NaviServer user)                 nsadmin
           ns_group               (NaviServer group)                nsadmin
                                  (Make command)                    make
                                  (Type command)                    type -p
           ns_modules             (NaviServer Modules)              nsdbpg
           with_mongo             (Add MongoDB client and server)   0
           with_postgres          (Install PostgreSQL DB server)    1
           with_postgres_driver   (Add PostgreSQL driver support)   1
           with_ns_deprecated     (NaviServer with deprecated cmds) 1
           with_system_malloc     (Tcl compiled with system malloc) 0
           with_debug_flags       (Tcl and nsd compiled with debug) 0
           with_ns_doc            (NaviServer documentation)        1

           pg_user                (PostgreSQL user)                 postgres
                                  (PostgreSQL include)              /opt/local/include/postgresql16/
                                  (PostgreSQL lib)                  /opt/local/lib/postgresql16/
                                  (PostgreSQL Packages)             postgresql16 postgresql16-server

The value of these configuration variables can be changed from the command line. In order to add the module "nssmtpd", we can call the script like in the following example:

$ ns_modules="nsdbpg nssmtpd" bash install-ns.sh
...
SETTINGS   build_dir              (Build directory)                 /usr/local/src
...
           ns_modules             (NaviServer Modules)              nsdbpg nssmtpd
...

But note, as it looks to me, the problem that you reported was not due to an incorrect installation of the nssmtpd module, but due to the fact, that you did not specify the "smtpdport" in the NaviServer configuration file.

You can set the "smtpdport" similarly as above from the command line, prefixed with "oacs_" as the following example, based on the configuration file that is provided via install-oacs.sh:

$ sudo oacs_smtpdport=2525 /usr/local/ns/bin/nsd -i -t /usr/local/ns/config-oacs-5-10-0.tcl -u nsadmin -g nsadmin
...
[-main:conf-] Notice: setting hostname to 'localhost' from default configuration
[-main:conf-] Notice: setting ipaddress to '127.0.0.1' from default configuration
[-main:conf-] Notice: setting httpport to '8000' from default configuration
[-main:conf-] Notice: setting httpsport to '' from default configuration
[-main:conf-] Notice: setting nscpport to '' from default configuration
[-main:conf-] Notice: setting smtpdport to '2525' from environment variable
[-main:conf-] Notice: setting server to 'oacs-5-10-0' from default configuration
[-main:conf-] Notice: setting serverroot to '/var/www/oacs-5-10-0' from default configuration
....
[-main:conf-] Notice: Use Tcl thread library /usr/local/ns/lib/thread2.8.11/libthread2.8.11.so
...
[-main:conf-] Notice: nsd.tcl: finished reading configuration file.
[-main:conf-] Notice: initialized locale en_US.UTF-8 from environment variable LANG
^C

But of course, you can also update the provided configuration file to alter the default from empty to 2525, or to set the port in the "ns/server/${server}/module/nssmtpd" section.

Hope this helps
