Comment 18 for bug 1085

I have some idea on solving this bug.

Its possible to add one more item on the popup menu(when you left click on the
from field) called copy header, and we can paste the whole header field
wherever we want.

alternatively, the item may also called view the header in plain text, in this
case, the whole mail header will display in a popup window in plain text, the
user may select the part they want to copy and paste somewhere else.

I'm not sure if anyone agree with my idea, if so, i can post the patch in one day.
