Hi I have a question about DNA, I live in a flat so deliverymen never leave packages in front of the door, they deliver them to the nieghbor.

Don't they attempt to first deliver to you?

Can I still do DNA if i have literally collected the package from the deliveryman?

If the package Is handed to you with only a signature to verify It, the DNA Is good to go.

My block of flats has cameras too, so if I claim DNA will the delivery compnay go as far as  trying to retrieve camera footage or is this not common practice? 

It's not common practice, but the possibility exists.
