Some mail sent through TT&T Maxnet SMTP is delayed for many hours
Today one of our Phuket customers asked us to investigate an email problem. They receive emails from two other Phuket companies with up to 17-hours delay. All other emails were received on time. After we checked the mail headers we saw what these two companies were sending through TT&T Maxnet SMTP server.
