Hi. Something strange happens with the server. This mail server supports 3 domains:domain1,domain2,domain3. When sending emails between these domains emails go without a problem, but if from any other - a problem - email is sent with outlook 2013, vistalba a read receipt,send email, and it comes in log it is nowhere, the notifications are not coming. After rebooting the server the email is delivered, the notification comes.
