When someone logs into the server these emails are sent out, one at a time per login. These emails are from the SMTP email I already setup. The MTA and PHP talk doesn't make any sense to me. If either of these were required then it would be impossible for me to receive the emails when someone logs in. But because this is working currently, just one at a time, I have to think the problem lies elsewhere. Thank you for your time and help Chefkeks, Ntozier, and Mfelber.
