I'm not saying that you shouldn't have used SMTP. It really is appropriate for this sort of thing. If you wanted an HTTP interface you might still make it inject messages into SMTP, with HTTP being only used for a browser UI, say, or with the HTTP server as a proxy for some reason. My objection had been to LDAP. LDAP is too heavy-weight by comparison to HTTP w/ a JSON API.
