Although you are more likely to send mail from a script in production,
you can send email using the REST API by sending an HTTP POST to
/openidm/external/email in order to test that your
configuration works. You pass the message parameters as POST parameters,
URL encoding the content as necessary.
The following example sends a test email using the REST API.
$ curl --header "X-OpenIDM-Username: openidm-admin" --header "X-OpenIDM-Password: openidm-admin" --request POST "http://localhost:8080/openidm/external/email? _from=openidm@example.com&_to=admin@example.com& _subject=Test&_body=Test"
