Answer 1

Your mailfunction will return successfully sent whenever the mail has successfully left the server. whether the server of the recipient picks up the email, and accepts it, is unknown to your mailfunction, and totally out of your hands. Since you mention that your testmails being sent to your personal emailaddresses all arrive, I assume that the problem is not in your PHP program, but in the recipients mailserver not accepting the email. Most probably they are being filtered as spam. A good way to prevent this is by using a real emailaddress on a valid domain and an SMTP server on that domain (same IP-Address) to send the mail from. Otherwise, many mailservers will see that the IP-address from the program sending the mail, and the IP-address of the mailserver in the "FROM" field are not the same, and label it as spam.
