Recently I posted about wanting to add an x-header recording a timestamp for changing the \Deleted flag, for purposes of doing expiry on mbox mailboxes. Timo replied:
Be sure to add it to mbox_hide_headers[] and mbox_save_drop_headers[] arrays in mbox-storage.c and hope that it doesn't exist in any of your existing mails. :) Other than that there shouldn't be problems.
I looked at the two places where X-Status was being written--mbox-save.c and mbox-sync-update.c--and tried adding this header. It didn't work. To test my sanity, I changed the string 'X-Status' in each of these to something else.
The mbox file still ended up with 'X-Status' written in it, and I can't for the life of me find any other code that might write that string. Timo? Anyone?
