someone tried to use my server as mail relay for sending spam
I don't know how the person got my server name/IP since the server is just online since a few days ...Anyway, someone attempted to use my server to send spam. I noticed this today while checking my Exim rejectlog. There are 5 attempts sending around 50 mails from 2 different mail accounts each time.
Exim logged the sender IP in the rejectlog. Can anyone tell me where i can report this abuse? abuse@maildomains and/or tracing the source ip and also notify the dial-up provider?
I haven't reported such things before so my question may sound stupid ...
Any help is really appreciated.
thank you,
Matthias
