Not quite sure where to send a feature request, so I try to follow the instructions for bug reporst. I would like to be able to search for emails with content with a given MIME type. The latest use case I ran into was my need to locate Notes and Exchange emails with text/calendar attachments, but I've also needed to find application/pdf and application/vnd.oasis.opendocument.text emails. Please consider extending notmuch to be able to search for specific mime types, for example using attachment:text/calendar or mime:text/calendar or something like that. Or perhaps just index up the mime content type value, to allow me to search for "tag:attachment and text/calendar". PS: Please CC me on replies, as I am not subscribed to the list. -- Happy hacking Petter Reinholdtsen
