It's a cryptographic signature showing that the email has been
cryptographically signed by David's private key, which you can then
'test' using his public key to make sure that he (the owner of the
private key specifically) was the one that signed (and therefore likely
sent) that message.

At least, that's how it would work for the GPG version of this tech.

I think this particular implementation David is using might be a little
different to the way GPG does it but it does the same sort of thing. 

In short, it's nothing nefarious, it's actually used to make email more
trustworthy in that it lets you know he sent it and not someone
pretending to be him.
