I'm kinda stuck with GMail's limited filtering. For all that a search company can provide, the ability to be able to search any part of the message including any part of the headers too, is missing.
To put the problem more specifically, I want to be able to filter incoming messages based on the "Delivered To:" header. This is because, I .forward my emails from another account to my GMail account (also serving as an archive). Now, the issue is that I can't find any way of filtering based on the headers of the message ! :(
Damn ! Any suggestions ?!
