Just a question

Why am I connecting successfully and asking smtp-server to send an e-mail successfully but the e-mail is never dispatched? It says that it is queued, however never sends. Look at my log:

This is because the smtp-server module is not an MTA application. You can use it in your own application as a SMTP front-end, so SMTP clients could send messages to your app using the SMTP protocol. What you actually do with that message (store it to disk, send it to another SMTP server etc.) is up to your own application logic. If you have not implemented relaying then your app acts as a black hole, it accepts the message but nothing is ever done with it.
