Fix it by adding this lines in sql_alias_access_policy.py .....
*************************
def restriction(**kwargs):
    conn = kwargs['conn']
    sender = kwargs['sender']
    recipient = kwargs['recipient']
    recipient_domain = kwargs['recipient_domain']

     # Add this two lines.....
    sender_domain = sender.split('@')[1]
    senderReceiver = {'conn': conn, 'sender': sender, 'recipient':recipient, 'recipient_domain':recipient_domain, 'sender_domain':sender_domain}

compile pyc files, restart iredAPD.... now work like a charm
