Use blackhole subdomain for sender addresses of verify probes.
These addresses need to be accepted on the MX:es, as recipients
sometimes phone back during the SMTP session to check whether the sender
exists.
Since a time-dependent suffix is added to the local part (cf.
http://www.postfix.org/postconf.5.html#address_verify_sender_ttl) it's
not enough to drop incoming mails to ‘double-bounce@fripost.org’, and
it's impractical to do the same for /^double-bounce.*@fripost\.org$/.
