Mail Delivery

Mail Delivery monitor checks your inbound and outbound mail servers by verifying delivery to both internal and external mailboxes. It lets you know more about the mail-user experience by testing every aspect of email delivery process and capturing the email round-trip time from 120+ global locations. Mail Delivery monitor sends emails to a designated SMTP server (similar to an email client), retrieves the emails using IMAP and POP3 protocols, and measure the round-trip time (from sender to receiver.) For validating the mail round-trip time, you can either use Site24x7's SMTP and POP3/IMAP Server configurations or use your own Server configuration. Please note that monitoring for mail delivery is not supported via On-Premise Poller.

Our monitoring data offers deep insight into the health and performance of your mail server environment; further allowing you to troubleshoot issues sooner, thus, ensuring high availability of your mail server infrastructure.

Features

The core features of the Mail delivery monitor includes:

• Ability to monitor incoming and outgoing mail servers through secure authentication.
• Calculate the Email round-trip time (RTT) of your mail server.
• Monitor Microsoft Exchange Server performance along with Email Server.

Adding a Mail Delivery monitor

General Settings

• Login to Site24x7 web client.
• Click Admin > Inventory > Monitors > Add Monitor.
• Select Mail Delivery in Add Monitor screen.
• Specify the following general detailsto add the monitor:
  • Display Name: Provide a name for the mail server for identification purpose.
  • Check Frequency: Choose the required polling frequency. The polling frequency can be set as low as 5 minutes or up to 1 day.
  • Connection Timeout: Specify the time in seconds for the connection to be established with the target server. The timeout should be between 0 to 30 seconds.
  • Location Profile: Select a location profile from the drop down list from where server will be polled from the selected location. 
    To know more, refer Location Profile.
    
    
  • Associate with Monitor Group(s): You can associate your monitor with multiple monitor groups by selecting the relevant monitor groups from the drop down list. This allows in logical grouping of your monitors. 
    To learn how to create a monitor group for your monitors, refer Monitor Groups.
  • Dependent on monitor: Select a monitor from the drop-down list to choose it as your dependent resource. You can add up to 5 monitors as dependent monitors. Alerts to your monitor will be suppressed based on the DOWN status of your dependent resource.
    

    Note

    • Configuring a dependent resource and suppressing alerts based on the dependent resource's status is part of providing you with better false alerts protection. Learn more about alert suppression at monitor level.
    • If you select None in the dependent resource field, alerting will progress as per your normal configuration settings. No alerts will be suppressed in this case as the monitor doesn't have any dependent resource.
    • Multiple monitor group support for monitors allow a monitor to be associated with multiple dependent resources in different monitor groups. If during a normal monitor status check, any one of these dependent resources' status is identified as DOWN, the alert for the monitor will be automatically suppressed. However, the dependency configuration at monitor level is always given the higher priority over any other monitor group level dependency configuration for suppressing alerts.
  • Check Mail Availability Alone: Toggle to Yes if you wish to verify the existence of emails by searching for them based on the subject line. No emails will be sent to the recipient, and emails will not be deleted.
    Toggle to No if you wish to send an email and search for it using the subject line after sending. 

SMTP Configuration

SMTP Configuration can be used to test the email delivery.

Use Site24x7's SMTP Server: Move the toggle button to Yes to select Site24x7's SMTP Server for testing email delivery. When you opt to use Site24x7 SMTP Server, the configured location profile will be overridden and Site24x7 default location will be used. Once selected, you'll be asked to enter the following fields:

• From Email Address: Email address from which the email will be triggered at the set check frequency.
• To Email Address: Specify the email address to which an email will be sent.

• If you've decided to use a custom SMTP Server to test the email delivery, move the toggle button to No. Then specify the following configuration details:
  • SMTP Host/IP: Specify your SMTP Host/ IP address. You can also use Find my SMTP Host to find SMTP Host.
  • Use Secure Connection (SSL): Use the toggle button to enable or disable a secure SSL connection.
  • Enable TLS: Use the toggle button to enable or disable Transport Layer Security (TLS).
  • SMTP Port: Specify your SMTP port. When SSL connection is enabled, the SMTP port is set to 465 automatically. The port number is set to 25 by default.
  • From Email Address: Enter your email address from which an email will be sent to test the SMTP host's availability.
  • To Email Address: Enter the Email address to which an email will be sent to test the SMTP host's availability.
    
    Note

    To successfully save your monitor, you're first required to validate the email address by clicking the verfication link sent to your To Email Address.

  • Configure Mail Server Authentication: Enable the toggle button to help the monitoring servers check the authenticated mail server. Provide the user name and password of your SMTP host.
  • User Name: Provide the user name of the SMTP host.
