also on the winsock smtp emailer

another problem is that using winsock to send the email,
it only works if I pick an email address that is on my domain.

when I pick an email address like [email protected]
it throws out error 550, saying that it doesn't recognize that user.

Any ideas?

Are you using Winsock for a client or server? Then it depends on how you are setting up ypur application and what SMTP commands you're using.

Honestly, I haven't tried to email programattically before.
I find it a bit confusing.

I have a website, say ggg.com and an email there, say [email protected]
I have a code that I can use to send messages from [email protected] to [email protected], but when I get the email in Outlook, the body of the message is not there, only the subject in the subject line.
Also, I can't send an email to anybody I want, only to myself.
The code is stuff I've pieced together from all the samples I'm finding here (pieced together because I can't seem to get a single piece of code to work without altering it).

I'll post the code below:

vb Code:

Option Explicit
 
Private WithEvents SMTP As clsSMTP
 
Private Sub Command1_Click()
Dim Winsock1 As New Winsock
 
With SMTP
 'who is the email from?
 .Sender = "[email protected]"
 'who is it going to?
 .Recipient = "[email protected]"
 'your SMTP server
 .SMTPhost = "mail.ggg.com"
 'optional subject line
 .Subject = "SMTP test"
 'make connection to the server
 
 .OpenMail Winsock1
 'did connection succeed?
 If Not .Connected Then Exit Sub
 'you can send as many lines as you want here
.Send "This is a test of your wonderful SMTP client!"
 'make sure you close or nothing will get sent
 .CloseMail
End With
MsgBox ("Success")
 
End Sub
 
 
 
Private Sub Form_Load()
    Set SMTP = New clsSMTP
End Sub

SMTP is a class and it's code is below:

vb Code:

Option Explicit
 
Private mvarConnected As Boolean
Private mvarRecipient As String
Private mvarSender As String
Private mvarSMTPhost As String
Private mvarSubject As String

I've tried to include the email body both in the sub and in the class itself, but it just doesn't show up.
Then of course the more serious issue of only being able to email myself so far.

Try this little SMTP application and see what it does for you. If the mail recipient requires Authentication then this will not do you any good as you will need to know what it is and how to use it.

I suspect the problem of no body being received is to do with this and the version of Outlook you're using:

Code:

---

  mvarWinsock.SendData "Body: THis is a test." & vbCrLf

---

Try

Code:

---

  mvarWinsock.SendData "THis is a test." & vbCrLf

---

or even this.

Code:

---

  mvarWinsock.SendData "Body:" & vbCrLf
  mvarWinsock.SendData " THis is a test." & vbCrLf

---

I assume that "Body:" is something that Outlook can expect as I don't see it defined anywhere in the SMTP Protocol.

BTW: Why have you modified the Class code ? It works perfectly 'as is'
