Howdy,
It depends on the exact situation, but the general-purpose answer is:
none. zero. zip.
The customer usually can't act on your information unless he can line
it up with an entry in his own logs. He needs lots of details in the
headers to figure out which computer or which of his users the message
came from. And he needs that information to determine whether the
message really came from his system -- headers get forged, you know.
If he can line it up with an entry in his logs then, if he's a
spammer, he knows what address the message was sent to rendering your
obfuscation pointless. And by now spammers are very good at list
scrubbing from the slightest bit of uniquely identifiable information
they can get back. Assuming they bother, which many don't.
It does depend on the situation though. You shouldn't be forwarding
the customer 200 spam complaints. After a small sample of messages he
either has enough information to track the source of the problem or he
is the problem.
Also, when I bounce spam, I scrub my antispam engine's report from the
bounce. No point telling the spammer how he failed to reach me.
