[dskinibbyb]

Hi to every one,
I am having a problem while sending mail from my application. iI want to send mail from my Vb.Net applications. and it is working fine in my system, but the problem is that when i try to run tha same application from another system where there is no iis installed, its giving me error mail not sent, and when i change the DeliveryMethod to network , giving me tha same problem...
So can anyone help me out with this problem..
The code is as below.
Public pInPassword As String
Public pOutMailId As String
Private Sub btnSend_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSend.Click
Try
'err msg = Request for the permission of type 'System.net.mail.smtpPermission, system, Version=2.0.0.0, Culture=neutral, PublicKey token= b77a5c561934e089' failed
Dim msg As System.Net.Mail.MailMessage
Dim objSmtp As New System.Net.Mail.SmtpClient("65.175.81.34")
msg = New System.Net.Mail.MailMessage(txtFrom.Text, txtTo.Text, txtSub.Text, txtBody.Text)
msg.IsBodyHtml = True
If check() = True Then
objSmtp.Credentials = New System.Net.NetworkCredential(txtFrom.Text, txtPassword.Text, "65.175.81.34")
objSmtp.DeliveryMethod = SmtpDeliveryMethod.SmtpDeliveryMethod.Network
objSmtp.Send(msg)
MessageBox.Show("Mail Sent Successfully....")
ClearForm()
End If

Catch ex As Exception
MessageBox.Show(ex.Message)

Hi dip_developer,
I asked my system Admin, and he said that smtp server is configured in server itself and he has given my the same Ip address of the smtp server so no need to configure the server..
Can you tell me what else i have to check?
this problem is really making me crazy.
thanks.
