Hi,
On some VM offerings you get a remote KVM, which would allow you to get
"physical" console access, and then you could encrypt the whole OS and
use the KVM to enter the key on reboot. That should prevent anyone in
the data centre from using the disk image without your key.

although I could set up a partition table that recognised the 4TB+

Hi All,

The resulting code would be open source (and happy for the author to put

Sorry, you are overestimating PostGrey’s ‘inteligence’.PostGrey doesn’t care
about what is waiting. It just tells the connecting server to go away and come
back later. When it connects again it just does the maths and if it is more
than 300 seconds it lets it through.
It then updates the databa

Those two do not contradict each other.
PostGrey simply stores an entry with a timestamp. It doesn't record that
anything is waiting, just when the last SMTP connection was made. If
someone sends an email to the same person from the same server every few
days they are never greylisted, and for th

AFAIK, due to the way Postgrey works, there is no list of “waiting” emails as

sent once.
So I really think the best you will be able to do is what has been done with
