SMTP Monitoring Tool Helps Troubleshoot Email Server Health Issues Faster

The Simple Mail Transfer Protocol (SMTP) enables a mail server and other message transfer agents to both send and receive digital messages. Think of SMTP as being the primary communication protocol behind the inbound and outbound transmission of emails. SMTP monitoring software not only authenticates an SMTP mail server’s ability to accept incoming sessions, but also positions an SMTP mail server to promptly respond. Each SMTP server maintains a unique address, and therefore needs to be set up within the mail client you are using.

SMTP monitoring software first opens a connection to the identified SMTP mail server. From there, an SMTP monitoring tool waits for the server to respond with an appropriately standard Service Ready Code 220 opening message. Upon the monitor’s receipt of the message, by transmitting a QUIT command to terminate the SMTP connection, safe disconnection from the server then follows. The test fails, however, if the mail server fails to respond, or comes back with an error code relaying that a given service is unavailable.

Remember, SMTP servers also remain configured to perform reverse lookups on each and every incoming connection. This process validates that the IP address of a specific SMTP client matches the domain or host submitted when authorizing each connection.

SMTP server monitoring is important for a few key purposes.

1. Provide data insights. SMTP server monitoring tools can help ensure servers continue to achieve
   full functionality and optimal performance.
   
2. Create mail client connections. SMTP monitoring establishes a mail client can create a new
   connection with a given SMTP mail server. To comply with the SMTP protocol, SMTP monitoring then verifies the
   mail server responds with the correct codes.
   
3. Ensure speed. SMTP monitoring is important for ensuring timeliness, making certain the server
   always responds within a required number of seconds.
   

SMTP server monitoring software like Server & Application Monitor works to quickly and effectively troubleshoot any issues pertaining to SMTP server health or performance. The right SMTP server monitoring tool allows for automatic
application discovery and server
monitoring.

SolarWinds SAM provides built-in templates to establish best practices across email servers. Monitoring the availability, resource capacity, and performance of Microsoft
Azure and Amazon AWS services can be quickly carried out using an efficient SMTP monitoring tool such as SAM.

SolarWinds SAM is designed to proactively monitor an SMTP server and check its ability to respond with the correct code when accepting incoming connections. SAM provides notifications when the response time falls below specified thresholds. It SAM is also built to resolve potential SMTP issues before they escalate to adversely impact email services. In addition to monitoring SMTP availability, SAM also comprehensively monitors server hardware health.

SAM SMTP monitoring software comprehensively tracks your multi-vendor server hardware performance and health status. It works to keep your critical mail server components up and running at all times, and alerts you before any component fails, with insights into data points for temperature, CPU, power supply, battery, fan speed, hard drive status, and more.

With SAM, you can rapidly diagnose and remedy server hardware issues across a broad breadth of servers and devices. SAM can be applied to Dell PowerEdge Blade, HP BladeSystem enclosures, HP ProLiant, Dell PowerEdge, IBM eServer xSeries servers, Microsoft
Windows Server, and VMware vSphere hypervisors.

Managing server capacity and forecasting resource availability is also made easy with SAM. The software provides built-in capacity forecast charts and relevant metrics to proactively determine when server resources approach warning and critical threshold levels. SAM makes accurate capacity forecasts by continuously tracking trend peak and average capacities. Server capacity issues can therefore more easily be identified and resolved before they begin to impact business performance or end-user productivity.
