    About Email notifications

    Email notifications are used to send emails about operations results, interactions, alerts.

    The option enables you to set up email notifications about events that occur during backup.

    It can help you to receive:

    • Operations results: Backup success/failure, etc.
    • Interactions: in case an operation requires User interaction.
    • Alerts

    See more in following articles:

    Web help: Configuring Email notifications for all machines

    Web help: Configuring notifications for individual backup plans

    You can also configure the severity of notifications you would like to receive

    Follow step-by-step instructions below to troubleshoot the issue. Complete prerequisites step before proceeding to error troubleshooting step.

    1. Prerequisites

    Check your mail server configuration. Acronis supports only SMTP protocol for sending messages. If you are trying to connect to Exchange server, make sure it is configured properly: Configuring Exchange Server for E-mail notifications (Use solution from Exchange 2007 for Exchange 2010 and 2013).

    In version 12.5 notifications are sent from Management Server only.

    If this requirement is met and issue persists, go to error troubleshooting step.

    2. Error troubleshooting

    Complete all steps before proceeding to collect information step.

    2.1 Antivirus Software

    If any firewall, antivirus or other security software is installed on the machine, make sure that the following Acronis processes are added to the list of trusted applications in the security software:

    Acronis Software: Making Acronis Products Compatible with Antivirus Software 
    Acronis Software: Making Acronis Products Compatible with Third-Party Firewall Software 
    For the full list of Acronis processes and ports used please refer here:

    2.2 Use correct Ports for the servers and encryption settings (Only for Custom mail server)

    Use correct Ports for the SMTP server.

    1. Typical port for unsecured connection: 25
    2. SSL: 465
    3. TLS: 587

    If you are not sure what port is your server is configured to be working on or about encryption you can use telnet to check: on a machine where your emails work fine in your email client use telnet to check above ports. If the telnet works on specific port - then your server listens on it and you can use the encryption settings from above for the particular port. E.G. if your SMTP server listens on port 465 then you most likely have to set encryption to SSL to send notifications.

    You can also check if specific settings are correct by manually sending email through telnet.

    2.3 Check Firewall and Network

    This is the most common cause in case notification is failing to be sent. Sometimes there are specific firewall rules that forbid specific machines from accessing the SMTP server. In this case, use telnet to check if the ports are accessible from the server. To find what ports you need refer to 2.2 of this article.

    2.4 Incorrect Settings specified for the SMTP server.

    Make sure that you are really using correct settings for the SMTP server. If you are using some kind of SMTP service provider such as Gmail then please choose the preset. If you have your own SMTP server please refer to its configuration to be sure.

    Do not enable encryption in Acronis Backup if it is not required by the server.

    If these steps have been executed and the issue persists, collect the information listed below and contact Acronis Customer Central for further help.
