When I use my yahoo email account, there is a link "Full Header" allowing me to view the full header of the email message that I received. This feature is extremely useful when I encounter an issue of tracking down who sent me a solicited email based on the sending IP address. This piece of information really helps me to diagnoise the issue of the sender masquerading somebody or even my email address.
BTW, I'm using OSS M3 version running on SLES9 box.
Would this feature be available in the next release ?
