Hello. I am developing a very simple smtp email sender.
I made it, i tested it, and it works fine but... only in my developer computer.
In all other computers that i install my application, it gives me "Failure sending email"
I am developing in the same network than the other machines, all computer under windows xp.
I found a difference, some of the computer uses netframework 3.5 and i was developing this application in netframework 4.0.
I tryed to change it to 3.0 and 3.5 but... with the same result...
Can it be because the class import?
in two days... i cant find the solution 
do i need to install something in the other machines? or add a reference file?
my code is this:
_______________________________________________
Imports System.Net.Mail
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
On Error GoTo 11
Dim msg As New MailMessage()
msg.From = New MailAddress("test@gmail.com", "Email Test")
msg.To.Add("myemail@yahoo.com")
msg.Subject = "Hey, this is a test"
msg.Body = "smtp email sending test"
Dim client As New SmtpClient()
client.Host = "mysmtp"
client.Port = 25
client.Send(msg)
MsgBox("OK")
GoTo 10
11:
MsgBox(Err.Description)
10:
End Sub
End Class
_____________________________________________________
Thank you in advance for your help.

Check the antivirus settings on the client. They may be interfering with sending of the mail.
