_INetSmtpMail, I get error 3 from example code what should i do to make it work?

[AnnoyingClown]

#include <Inet.au3>
#include <MsgBoxConstants.au3>

Local $s_SmtpServer = "mysmtpserver.com.au"
Local $s_FromName = "My Name"
Local $s_FromAddress = "From eMail Address"
Local $s_ToAddress = "To eMail Address"
Local $s_Subject = "My Test UDF"
Local $as_Body[2]
$as_Body[0] = "Testing the new email udf"
$as_Body[1] = "Second Line"
Local $iResponse = _INetSmtpMail($s_SmtpServer, $s_FromName, $s_FromAddress, $s_ToAddress, $s_Subject, $as_Body)
Local $iErr = @error
If $iResponse = 1 Then
    MsgBox($MB_SYSTEMMODAL, "Success!", "Mail sent")
Else
    MsgBox($MB_SYSTEMMODAL, "Error!", "Mail failed with error code " & $iErr)
EndIf

Success:	1.
Failure:	0 and sets the @error flag to non-zero.
@error:	1 2 - Unable to start TCP 3 - Unable to resolve IP 4 - Unable to create socket 5x - Cannot open SMTP session. x indicates the index number of last command issued to the SMTP server. 50x - Cannot send body. x indicates the line number of $aBody (first line is 0). 5000 - Cannot close SMTP session   I get error 3 from example code what should i do to make it work?

You need to modify the code so that $s_SmtpServer points to a valid SMTP server.
