Hi Micheal,

If it concerns dynamically allocated IP addresses I second this opinion, however if it costs you no work to identify the customer, why not forward the message? As long as it is not too much work, the customer will be happy or at least ammused about the mail. So if it costs you significant work to find out who had the ip address, silently discarding the mail is the way to go in deed.
As you have already seen in this thread, an ISP have to give information to UVEK-DBA only.
I'm not a lawyer, but if the ISP forward the information to the client, and if the client contacts the original sender of the mail, it's somthing like an "indirect leak of information". There is no clear law on this subject (at least on Switzerland).
As an ISP, I would ask my lawyer before doing something.
Regards,
Vincent M.
