hi list,
Under MAIL EXCHANGER POLICY TESTS
i see this:
By listening on both primary and backup MX addresses,
postscreen(8) can deny the temporary whitelist status to
clients that connect only to backup MX hosts.
I dont get it at "all".
When my backup MX is not on the same Server as postfix,
how can it listen to the backup mx adress?
or do i get this totally wrong?
marko
