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$/.
