in outlook2010 (windows), there is a very interesting feature that i try to reproduce into zimbra. :
the abitity to be alerted/noticed (dialogue box or autoself-email) of the none-reception of a email.

for example, if every sunday you must receive a email from X and you don't have it one time, then outlook notices you by a dialog box (before, you can set up dialog box or autoself email, program the period...etc).

can we do the same feature in zimbra in a alternate way?
