(Visual Basic) Getting TO / CC Email Recipients
Demonstrates how to examine the TO and CC recipients of an email.
Note: BCC recipients are generally NOT found in the email's MIME. "BCC" is a "Blind Carbon Copy", which means that the TO and CC recipients of the email should not be able to see the BCC recipients. If the BCC email addresses were found in the MIME header, then they would no longer be "blind" because nothing would prevent the other recipients from seeing the list of BCC recipients.
To understand how BCC recipients receive an email, I recommend reading this blog post: SMTP Protocol in a Nutshell. The BCC recipients are passed to the SMTP server in “RCPT TO” commands.
' An email can have any number of To, CC, or Bcc recipients. Dim email As New ChilkatEmail2 Dim success As Long success = email.LoadEml("sample.eml") If (success <> 1) Then Text1.Text = Text1.Text & email.LastErrorText & vbCrLf Exit Sub End If ' It doesn't matter if the email object was loaded from a .eml file, ' or if it was downloaded from a POP3 or IMAP server. ' The methods and properties for examining the TO and CC ' recipients are the same. Dim i As Long ' The number of TO recipients is found in the NumTo property Dim numTo As Long numTo = email.NumTo ' Iterate over each TO recipient If (numTo > 0) Then For i = 0 To numTo - 1 Text1.Text = Text1.Text & "TO Friendly Name and Address: " _ & email.GetTo(i) & vbCrLf Text1.Text = Text1.Text & "TO Address: " _ & email.GetToAddr(i) & vbCrLf Text1.Text = Text1.Text & "TO Friendly Name: " _ & email.GetToName(i) & vbCrLf Text1.Text = Text1.Text & "---" & vbCrLf Next End If ' The number of CC recipients is found in the NumCC property Dim numCC As Long numCC = email.NumCC ' Iterate over each CC recipient If (numCC > 0) Then For i = 0 To numCC - 1 Text1.Text = Text1.Text & "CC Friendly Name and Address: " _ & email.GetCC(i) & vbCrLf Text1.Text = Text1.Text & "CC Address: " _ & email.GetCcAddr(i) & vbCrLf Text1.Text = Text1.Text & "CC Friendly Name: " _ & email.GetCcName(i) & vbCrLf Text1.Text = Text1.Text & "---" & vbCrLf Next End If
