Furthermore, you appear to think that all DNSBLs are reactive in
nature. This is not true; there are at least a few DNSBLs that
proactively list "large indistinguishable pool" addresses. In at least
one case, the pools are submitted to them by the providers that run the
pools. Using such a list puts a substantial crimp in direct-to-MX
And the providers lie in those list. I know my provider
lies yet I can't get the list operator to remove the entry
or the provider to provide truthful data.
The address is listed as "not supposed to be sending email".
The provider blocks port 25 outbound by default and has a
remove block support that doesn't remove the address from
the list when the port filter is removed.
