Currently, 'Exception' ativity type is visible in dropdown list of schedule
activity. It is used by the system to generate warning activities on records.
It is not meant to be used by the user when scheduling activities manually.
By, giving active=false on mail.mail_activity_data_warning, we can hide
'Exception' activity type in dropdown list for user but available for the
system to generate warning.
