'  email addresses are flagged as invalid.

'  Return all bad email addresses in saBadAddrs:

Set saBadAddrs = mailman.VerifyRecipients(email)
If (saBadAddrs Is Nothing ) Then
    Response.Write mailman.LastErrorText & "<br>"

Else
    '  List the invalid email addresses:
    If (saBadAddrs.Count > 0) Then

        n = saBadAddrs.Count
        For i = 0 To n - 1
            Response.Write saBadAddrs.GetString(i) & "<br>"
        Next

        '  Examine the SMTP session log to see how the email
        '  addresses were caught:
