[RESOLVED] [2205] specify the mail server address

Hi,

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

Code:

---

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:

Code:

---

 
Dim smtp As New SmtpClient("127.0.0.1")

---

Thanks in advance

From you isp or from whoever manages your internal e-mail server.
eg my isp is post.demon.co.uk if you ping this you get the ip 194.217.242.89
but you better of using the name rather than the ip.

Hi,

I'm using:

Code:

---

Dim ip As IPAddress = Dns.GetHostAddresses(Dns.GetHostName())(0)
MessageBox.Show(ip.ToString)

---

But the numbers that I get, they are not good.

How do you send e-mail using a mail client? You ask your ISP for the address of their SMTP server and you type it in. The same is true of sending mail using VB. You get the address of your ISP's SMTP server and you type it in. If you already have the server name then you don't need to get the IP address because the SmtpClient constructor will accept either. Get the address of your SMTP server and just type it straight in, either at design time if you want it hard-coded or run time if you want to be able to change it.

This is working:
Dim smtp As New SmtpClient("smtp.internet service provider")
'
But I want to give the program to my friend and he will send me an Email From my program.
The program need to know the ("smtp.internet service provider") of my friend.

Do you know the code to find the ("smtp.internet service provider")

There is no code to find. Like I said, you can specify the value of the SMTP server name at run time if you want it to be variable. I'm quite sure that you've provided a means for the user to enter a string value before. You need to do it again, e.g.

VB Code:

Dim smtp As New SmtpClient(Me.smtpTextBox.Text)

Hi,

Thanks jmcilhinney

and to Everybody that try to help.

I don’t have a choice I'll use smtp.gmail.com

Just ask your ISP or tell your friend to ask his ISP for the their SMTP server (e.g. Adelphia = mail.adelphia.net). Every ISP must give its users an SMTP, Gateway, DNS etc... or find one for free like dyndns.org = mail.dyndns.org. Just need to make sure that these free smtp servers can relay to your SMTP. Good luck!

Hi,

I want to build a clever program to a stupid user.
I'll use smtp.gmail.com

Thanks
