Switching to the dev list. Tomaz, the link Kabir provided shows an example of injecting a SocketBinding service into a service that needs a socket and then using that to create the socket. The SocketBinding service is created as a result of a <socket-binding> element in domain.xml or standalone.xml. The different thing about your mail service is the sockets involved are not being opened on the AS itself; what your subsystem has is configuration for a remote socket. The domain model doesn't currently support including a <socket-binding> configuration for a remote socket; that's the thing that would need to be added to tie it all together. https://issues.jboss.org/browse/AS7-1614 is the JIRA for that; if you want to take that on, that would be great!
