Relay access denied

Permissions issue is the first issue to clear up. Perhaps a password mismatch?

Since this is a school project, can the teacher of the course be of assistance?

E-mail servers don't typically allow remote relay by default.

For Exchange you need to create a new Receive connector that allows anonymous relay.
