VB SmtpSendRawCommand

Sep 01 '16 at 13:42

Ok , I have a strange output from SmtpSendRawCommand when doing this :

 Dim rasp As String = String.Empty
 rasp = mailman.SmtpSendRawCommand("MAIL FROM:root\r\n", "ascii", False)
 rasp = mailman.SmtpSendRawCommand("rcpt to:test", "ascii", False)

I get 530 SMTP authentication is required. , however ,when I telnet into the same server, same commands, I get this : alt text
