TLS via SMTP is opportunistic which makes connections vulnerable to man-in-the-middle-attacks. In order to prevent mitm-attacks, DANE could be used. The sender-server will first check the domain-records if dnssec is in use(and valid) and if a TLSA-record is published(and valid). If a TLSA-record is valid and matches with the certificate of the recipient-server the connection could be encrypted and the encryption is verified.
Every time I replace an old hard disk by a newer or bigger one I think that I'll wipe it later. Now I have a big amount of hard disks to wipe. Since wiping takes ages, I don't want to use my personal computer for that. I would prefer a small device with low energy consumption just for wiping. That's why I am going to build a "Nukestation". Basically it's just a Raspberry Pi with nwipe on it and a udev-rule for automatically wipe attached hard disks. But some extras would be nice...
