5.4 Attachments and MIME-parts

E-mail messages can be though as a series of “MIME-parts”, which are sections of the message. The most prominent is the ’body’, that is the main message your are reading. Many e-mail messages also contains attachments, which MIME-parts that contain files10.

To save such attachments as files on your file systems, the mu4e message-view offers the command mu4e-view-save-attachments; default keybinding is e (think extract). After invoking the command, you can enter the file names to save, comma-separated, and using the completion support. Press RET to save the chosen files to your file-system.

With a prefix argument, you get to choose the target-directory, otherwise, mu4e determines it following the variable mu4e-attachment-dir (which can be file-system path or a function; see its docstring for details.

While completing, mu4e-view-completion-minor-mode is active, which offers mu4e-view-complete-all (bound to C-c C-a to complete all files11.

5.4.1 MIME-parts

Not all MIME-parts are message bodies or attachments, and it can be useful to operate on those other parts as well. For that, there is the function mu4e-view-mime-part-action (default key-binding A). You can pass the number of the MIME-pars (as seen in the message view) as a prefix argument, otherwise you get to get to choose from a completion menu.

After choosing one or more MIME-parts, you are asked for an action to apply to them; see the variable mu4e-view-mime-part-actions for the possibilities; and you can add your own actions as well, see MIME-part actions for some example.



Attachments come in two flavors: operating on them; everything that specifies a filename is considered an attachment
