This folder-based searching is very handy. However, I have a scenario in which I'd prefer to consolidate mail to multiple addresses into one or a small number of physical mail folders. Thus, what I really want to search on is not the mail folder name, but the Delivered-To: header.
Can someone tell me if there is any easy way to restrict a search to the Delivered-To: header, or to add custom header support to notmuch? Sorry if this is a very basic question. I've just started checking out notmuch and really like what I see so far. My inability to figure out how to search unambiguously for Delivered-To headers looks like it could be the biggest obstacle to switching from Wanderlust (which lets me customize search for arbitrary headers listed in elmo-msgdb-extra-fields). Thanks.
