[RESOLVED] [2205] specify the mail server address

[yulyos]

Hi,

I copied this code from web site:
http://www.systemnetmail.com/faq/2.1.aspx

Sub PlainText() 
'create the mail message 
Dim mail As New MailMessage() 

'set the addresses 
mail.From = New MailAddress("[email protected]") 
mail.To.Add("[email protected]") 

'set the content 
mail.Subject = "This is an email" 
mail.Body = "this is the body content of the email." 

'send the message 
Dim smtp As New SmtpClient("127.0.0.1") 
smtp.Send(mail) 
End Sub 'PlainText

My question is:
How can I get these numbers:

  
Dim smtp As New SmtpClient("127.0.0.1")

Thanks in advance
