Disclaimers

I have been looking keenly at email disclaimers attached emails mostly from those using their company/org domains. To me the disclaimers don’t seem to make alot of sense.Are they enforceable? or can a company be indemnified in case the information received through their domains cause damage to a third party?What do people think?I personally think that specialists in cyber law should carefully delve into this and come up with some concrete and comprehensive legislation on disclaimers. I’m not a lawyer but when i read the disclaimers, i find them quite contradictory.I would love hear your take on this!
