Because you cannot block hosts in mailman which aren't used for the
construction of mail addresses. So I can block "foobar _AT_
linkedin.com", but cannot block "foobar _AT_ example.com" where mail
enters our system from linkedin.com.

I would have to do that on the system level (well, mailserver) - but I
won't do that for several reasons.
