Hi,
i can see the logs and so on but i am not really sure if someone is sending mails from my server.
I have lots of sasl auth failed but also some startssl messages in the log.
I am not 100% sure how to know when someone really sends successfully mails over my server.
Can someone tell me how to really interpret these logs and when someone actually made it.
I have set the security with best conscience and all the sender_restrictions etc. but I'm not quite sure if it is really optimal and no one can send except my domain.
Maybe someone who knows more about mailserver and logs can explain this in more detail.
thanks
