We are currently facing some security issues with an exisiting email server under Ubuntu/Postfix. Since around 2 weeks the server started to send a large amount of emais to random email addresses acting like a relay.
We took some measures (change of admin password, relay denied, etc.) with no success so far. We are thus looking for an expert to sort the issue and explain to us how to avoid such situation in the future.
