'  This example requires the Chilkat API to have been previously unlocked.
'  See Global Unlock Sample for sample code.

'  The mailman object is used for sending and receiving email.
Dim mailman As ChilkatMailMan
mailman.Initialize("mailman")

'  Use your SMTP server hostname.  This example uses office365, but it could be any SMTP server..
mailman.SmtpHost = "outlook.office365.com"
mailman.SmtpPort = 587
mailman.StartTLS = True

'  Set the SMTP login/password
mailman.SmtpUsername = "OFFICE365-SMTP-LOGIN"
mailman.SmtpPassword = "OFFICE365-SMTP-PASSWORD"

'  Create a new email object
Dim email As ChilkatEmail
email.Initialize
email.Subject = "Testing for Chilkat SMTP API..."
email.Body = "Testing for Chilkat SMTP API..."
email.From = "Chilkat Support <my-office365-user@mydomain.com>"
email.AddTo("Chilkat Support", "support@chilkatsoft.com")

'  For whatever reason, the iPhone's email program requires
'  images in HTML to be referenced by Content-ID.  Therefore,
'  we must add the image like this:
Dim contentIdStarfish As String = email.AddRelatedFile("qa_data/jpg/starfish.jpg")
If email.LastMethodSuccess <> True Then
    Log(email.LastErrorText)
    Return
End If


'  The src attribute for the image tag is set to the contentIdStarfish:
Dim sbHtml As ChilkatStringBuilder
sbHtml.Initialize
sbHtml.Append("<html><body><p>This is an HTML email with an embedded image.</p>")
sbHtml.Append("<p><img src=" & Chr(34) & "cid:CONTENT_ID_STARFISH" & Chr(34) & " /></p></body></html>")
Dim numReplacements As Int = sbHtml.Replace("CONTENT_ID_STARFISH", contentIdStarfish)

email.SetHtmlBody(sbHtml.GetAsString)

success = mailman.SendEmail(email)
If success <> True Then
    Log(mailman.LastErrorText)
Else
    Log("Mail Sent!")
End If
