There's also people, out there, asking loudly for filter-free accounts
and redirecting it on another (filtered) account, just to hit the spam
button for every junk they receive from the forwarding.
Or, similar story: company here in Italy with remote office in US. info@
role account is an alias sending to both Italian people and to an AOL
account used by the remote office.
Italian users give opt-in in order to their suppliers in order to
communications from their Italian suppliers. The US guy hits the spam
button for each one he receives. I (the forwarding ISP) receive AOL's
FBL for each... :-\
Who's reputation is expected to be damaged? ;-)
The one who's forwarding unwanted email. Ideally, you're using SRS to
forward from a specific address, so the reputation can be assigned to that
address rather than the IP address. Then, when AOL stops accepting the
email, the company will change their subscription. Perhaps you should
forward the reports to info(_at_)(_dot_)(_dot_)(_dot_)
If the messages contain DKIM sigs, then address based repuation is already
feasible, but SRS and SPF would make it feasible otherwise.
It's for examples like this that you need a "Block" as well as a "Report
for spam" button - like Twitter has.
