When we are using the Java Aspose SmptClient to send the emails, we are not getting any exception in case if there is a partial delivery failure, i.e. the send mail works for some recipients and not for some other recipients. We are getting an exception only if the email delivery fails to all the recipients in the email. This seems to work ok when we use the standard javax.mail.Transport.send(). We would like to know how we can configure the Aspose SmtpClient to notify us on partial delivery failures.
