Rebex SMTPException Response code list

Hi

We are using Rebex for sending web mail.
* While sending mail getting different SMTP exception response code for same reason with different mail client.
* Getting same SMTPException response code for different reason.
Ex : in Yahoo Response Code : 535 is for wrong password and as well as for Less secure app turned off exception.

So is there any Rebex document, I can find SMTPException specific to Rebex SMTP mail API's??

This will be helpful to handle all exception Rebex API throws, Instead of doing just trial and error.

Thanks,
Mohan
