Now, scroll down and to the newly created attachment edit section . In the window that pops up, find the file in your directories that you want to attach. Finally, if you want to see a picture of this editing interface, please take a look at the documentation for the attachment heading . Do exactly the same as you would do to attach a picture or any other binary file. One note however.
Emails often have totally unintuitive file-names.
Or worse, the mail system you use may not give you direct access to the individual files containing the messages. This basically involves using the attachment browsing interface and then going through the system updating stale pointers. Make sure that the confirmation button is checked. A deletion is forever. So, please be careful with it.
