according to the status:
["waue_success_1_Log"]=> string(51) "Sending To: email@example.com... Success
the email is being sent to the SMTPO server.
if you are not receiving the email, there are 2 possibilities:
1) The SMTP Server is refusing to relay the email
2) The email is being trapped as spam
for number, you will need to check with the host and have them look into the SMTP server error logs, for number 2, check your spam filter.
