Someone died recently in the nether in smp7 carrying a stack and a half of glowstone dust, some magma cream and full iron armor and tools. I picked up all that, created a chest and put everyting inside it. If that belongs to you, just head over to your death point and you will find your stuff.
Unfortunately, not everyone knows where they die, so it could be anyone's and someone is likely to loot the chest if they find it.. I have made graves for unknown people in the servers and usually leave their stuff in a box nearby, but I never really know for sure if the person they belonged to got them back.. <,<
I can always hope. And when I pass by that location again and see the chest gone, I'm going to assume the rightful owner got it. It's better for mental health.
