Emailed Files

Create a Mailbox for your Moodle Instance (e.g. moodle@yourorganization.org / moodleXY@gmail.com).
Users can send mails to this mail-Address and import email-attachments from their mails as files.
The main advantage of using the email repository is that you can use nearly every mailbox that provides access via imap, which is rather easy. Any user can send an email to this address e.g. moodle@yourorganization.com or ourmoodle@gmail.com. As long as the senders mail-address is the same as the mail-address of the moodle-user the user can import the attachment into moodle.
On the configuration page of the moodle plugin there is a parameter to specify after how many days old emails should be deleted.
