SMTP monitoring check

How does the SMTP Monitoring work?

The SMTP monitoring check is a part of the ClouDNS motoring service, which scans the chosen SMTP port number on the given IP address. If the connection is unsuccessful, the check is marked as DOWN.

Simple Mail Transfer Protocol (SMTP) is a communications protocol that is primarily used for sending and receiving email messages between servers. SMTP is essential for email communication, ensuring that messages are sent and received accurately and efficiently. It operates over TCP, providing reliable delivery of emails by establishing a connection before transmitting data and ensuring that the data is delivered without errors.

Why do you need to start using SMTP?

SMTP is suitable for any application that involves sending emails, including newsletters, notifications, and alerts. Reliable email delivery is critical for businesses to communicate effectively with their clients and users. SMTP ensures that emails are not only sent but also properly routed and received, minimizing the chances of emails being lost or marked as spam.

Why is it important to monitor SMTP?

SMTP monitoring is an essential part of network management and email system administration, as it provides administrators with the ability to detect and respond to email delivery issues, track email traffic patterns, and uncover inefficiencies. It is a proactive approach to email management, allowing administrators to identify and respond to potential issues quickly before they become significant problems. Additionally, SMTP monitoring offers real-time results, ensuring that administrators are always aware of any changes in the email system and can take immediate action if needed. In other words, monitoring SMTP is crucial in maintaining the health and security of email communications across all organizations.

Debugging

Each Monitoring check provides a debugging option which you can use to find out where the problem comes from using Traceroute information - The traceroute command is used to determine the path between two connections. Often a connection to another device will have to go through multiple routers. The option can be found in the Monitoring check settings page on the right side of the "Uptime changes section".

Which port to use for SMTP monitoring check?

Regarding SMTP monitoring, it is crucial to choose the right port for each system to ensure the safety and integrity of the email communications. The most popular ports used for SMTP monitoring are:

  • Port 25: Standard port for SMTP communication.
  • Port 465: Secure SMTP port used for sending emails with SSL.
  • Port 587: Preferred port for email submission with TLS.

Monitoring these specific ports ensures that any issues related to email sending and receiving can be promptly detected and addressed. Note that there are other ports used to monitor SMTP, depending on the specific use case.
