Why are you spamming me?
Many people see e-mails with the following header:
X-Scanned-By: MIMEDefang x.y
(www dot mimedefang dot org slash enduser)
That does not mean that Mimedefang administrators are in any way associated with the e-mail.
It simply means that your ISP, or the ISP of the sender, is using the MIMEDefang mail scanner to scan for viruses.
