AWS SES - SMTP eMail as MMS to @vzwpix.com - MAILER-DAEMON@us-east-2.amazonses.com

When sending an AWS SES SMTP eMail to MMS text message with attached image seems to send without any .NET error but is never delivered. I think it got bounced?

ie myphone#@vtext.com works send text but removes attached image where myphone#@vzwpix.com does not work with or without image attached and is never delivered. thoughts?

Integrate using SMTP Relay code below.

   Try
        Dim SmtpServer As New SmtpClient()
        Dim mail As New MailMessage()
        SmtpServer.Host = "email-smtp.us-east-2.amazonaws.com"
        SmtpServer.Credentials = New Net.NetworkCredential(tbUserName.Text, tbPassword.Text)
        SmtpServer.Port = "587"
        SmtpServer.EnableSsl = True
        mail.From = New MailAddress(tbFromName.Text)
        mail.To.Add("xxxxxxxxxx@vzwpix.com")
        mail.Subject = tbSubject.Text
        mail.Body = tbMessage.Text
        SmtpServer.Send(mail)
        MsgBox("eMail Sent Successfully")
        btnSend.Enabled = True
    Catch ex As Exception
        MsgBox(ex.ToString)
        btnSend.Enabled = True
        Exit Sub
    End Try
