Login Disabled clients do not receive ticket updates from us at all

Blocked clients in FraudMind + Login Disabled do not receive email updates for tickets when we reply to the ticket. The system is not sending the notification at all. This is rendering them locked out of disputing their suspension hence prompting them to create new accounts or email us from different emails.
If the Login is not Disabled they do receive the emails fine and the problem seems to occur only when their login is disabled.
