SmtpMessageRecipientSubmittedEventArgsAllowRefusedRecipient Property |
Namespace: MailBee.SmtpMail
You can set this property value to false in case if you encounter that an important recipient was rejected by the server (this requires you to allow failed recipients first by setting SmtpServer.AllowRefusedRecipients to true.
Or, you can leave SmtpServer.AllowRefusedRecipients in its default state false (so that failed recipients would generally not be allowed) but set AllowRefusedRecipient to true for some particular recipients which you find not important.
