Hi! 

The Moodle platform I'm administrating has many students who have an e-mail address that can't be found. Everytime a teacher tries to send messages to all the students in a given course I receive many e-mails by every message, and this is linked to my cellphone, of course. I can't find an option that can help me with this. 

Can somebody help me with this? 

Thanks.
