cubicweb-drh #246932 faciliting email use and integration [open]

when an application arrives by email, it would be nice to be able to redirect it to an alias as follows (b is for bounce in mutt):

b drh+[abcde]   # pour +1 +0 0 -0 -1

The hrm cube would then:

• import the email
• create a person and link to it the attached documents and the emails
• add an note from the user who bounced the mail (see Resent-From header)
• detect duplicates and only add a note if the message-id already exists
