Very strange indeed. web-net.gr <http://web-net.gr/> is not in any header that 
I could see. Is there something in the links pointing to that? 

The return path for that message is elmetal.gr <http://elmetal.gr/> and 
include:_spf.google.com <http://spf.google.com/> is in that SPF record and that 
IP is in there. Looks like Gmail is just confused. Is it one message or many?
