 2. Ignore the `.json` files in notmuch. Any tags listed in `new.tags` will be added to newly pulled messages. Process tags on new messages directly after running gmi, or run `notmuch new` to trigger the `post-new` hook for [initial tagging](https://notmuchmail.org/initial_tagging/). The `new.tags` are not ignored by default if you do not remove them, but you can prevent custom tags from being pushed to the remote by using e.g. `gmi set --ignore-tags-local new`. In your notmuch config file (usually `~/.notmuch-config`):
 
-```
-[new]
-tags=new
-ignore=/.*[.](json|lock|bak)$/
