Hi All,

We have an ex-employee : name 'X' with work email address as "abc" and home email address as "xyz".

After few months X has applied for a job requisition as an ex employee using the home email address. All the Job Application notifications are triggered to Home email address of X till Accepting the offer. We have one notification that is setup for external category to send Congratulation email after accepting the offer. This notification which is supposed to trigger to home email of X the system is triggering the notification to work email address which is "abc".
