I'm using local email, not IMAP, but I map my "d" key to:

     <save-message><enter><next-undeleted>

and I've got:

     save-hook . archive-folder-name-here

so that the default save location (implicitly used in the macro) is the 
archive folder for my current folder.

Persoanlly, I do not have a trash folder; I just "archive" messages. A 
bit like the GMail model is (or was? dunno any more).
