In a lot of cases, that seems to boil down to "sending a legitimate 
email to a recipient who once *asked* to be sent such email, who has now 
forgotten they signed up in the first place".  :(

There's not much a sender can do about that - particularly for periodic 
emails of the type *many* companies send to customers (or potential 
customers) who have signed up for these messages.

Exactly the point I was trying to make earlier. As an ESP (email service 
provider), we have a tough job in separating the wheat from the chaff. 
When you have just under 10,000 customers and 12 IPs, it's a little 
difficult to know who sent to a spamtrap when we aren't even given the 
most basic information about a message.

Not only can the sender not do anything about the reporting and getting 
blacklisted, but the way spamcop sometimes (always?) lists the host, 
they can't find out which of their senders was involved, and thus have 
no hope of figuring out which of that sender's recipients is responsible.

Kind of hard to solve a problem when you're just being told "something 
is wrong" and _nothing_ more.  Which is the case when a spamtrap was 
involved.
