If the original recipient forwards an e-mail they receive , and then someone replies to that e-mail , can the original sender see this reply or the forwarded message ?
We want people to be able to e-mail themselves the documents they 've worked on , so they enter their sender e-mail address and their receiving e-mail address -LRB- usually the same address -RRB- and then our system sends it via our SendGrid IP . The emails are being blocked . What are some ideas ?
