Hi, Two questions: 1) How does notmuch detect the presence of attachments? I have some messages that have attachments (which I can see and open when reading the message), but for which the 'attachment' flag is not set (and therefore don't show up in a search like "from:myfriend AND attachment:pdf"). How can I try to work out what is going on? 2) Is there an option for notmuch to also index the text of attachments (like recoll does, which also uses xapian)? People tend to save attachments with really useless filenames (report2.pdf...), what I'd like to be able to do is a search like "from:mycolleague AND attachment:pdf AND attachmentcontains:ourproject" Thanks for your help. Notmuch is already very useful! M.
