Problem: The DEC's anti-virus software (TrendMicro) which is installed on their email servers results in the delivery failure of email notifications and password reset emails to any DEC email account (staff and student).
Solution: Edit your Moodle profile and Notification Options to use an email address that is NOT your DEC one (eg a Gmail one setup specifically for work purposes). Similarly ask students to edit their profiles to use a non DEC email account.
Note: If yourself or a student is unable to rest their own Moodle password due to this issue, please submit a tech ticket stating this (ie that the student is a gov student and is therefore unable to reset his/her own password) and requesting that the student's password be reset manually, and also their email address changed in Moodle (provide details in the ticket).
