There are ways to attempt to extract header info, but the problem is that saving the message so you have something to look at - or even just looking at it for too long, gives the spammers what they want. They know that you received it.
And there is no useful purpose in finding out who they are, because even if you do, you can't (under current laws and policies) do anything to stop them. The ONLY reason to worry about who they are is if they are doing something that is CLEARLY ILLEGAL, and would be of sufficient weight to enlist LAW ENFORCEMENT AUTHORITY to take care of it.
Set your filters (but blocking their address is ineffective, because it's a fake and they'll have three new ones tomorrow). Don't open. Don't worry. DELETE.
