They are not "official spammers". They notify you about serious
configuration problems on your end.
(It's only a configuration problem because Spammers abuse open relays,
but nevertheless, closing the relays is the ONLY way to slow down
Spammers -- and save your resources by not giving them to Spammers --
and thus, you do want to know if you have open relays).

You're only notified if you're listed as contact person in the RIPE
(or some other IRR) database

They do. When one of our customers was found to be vulnerable, they
were notified (to "postmaster@localhost") and I got a copy
as well (being listed as tech-c:).

No. You're responsible for network abuse done by your customers.

If your customers abuse the net, you will be blaimed -- it's not easy
to contact individual customers, but it IS easy to contact the ISP in
question to stop net abuse.

I can't do anything about it -- you can. For example, do not allow
incoming SMTP connection from "the Internet" to dynamically assigned
IP addresses. Or educate your users.
