5 good reasons to choose PRTG as your email monitoring tool
iWhat is a sensor?
In PRTG, “Sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.
With PRTG, you can opt for a license and get access to all the tool’s sensors and features. Sensors, a notification system, technical support – PRTG is all-inclusive.
The alarm system can be customized according to your own individual needs. You get to specify when – and how – PRTG should sound the alarm. As a result, you’ll only receive messages when it’s absolutely necessary.
With PRTG, the first 100 sensors are free and never expire. The free trial version of PRTG is perfect for getting a simple and straightforward feel for our monitoring software. If PRTG meets your expectations, you can then choose a license that works for you.
PRTG comes with several preconfigured sensors for your email and mail server monitoring, including POP3, IMAP, and SMTP sensors. That makes the setup process both quick and easy.
In addition to email, PRTG monitors all your hardware, virtual environments, and applications. You therefore get an overview of your entire network.
An introduction to email monitoring with PRTG
Email monitoring for applications such as backup software:
Many administrators use email monitoring so they can constantly check the status of their backups. This is because it’s too difficult to keep an eye on all statuses when so much different backup software (e.g. for virtual environments, databases, and email) is being used. Most backup services send emails to indicate whether or not a backup was successful. But other applications and programs often send important messages by email as well. PRTG automatically checks the contents of all these emails, and can therefore monitor the status of each of your applications.
Administrators receive messages from backup software in their inboxes. But these messages, many of which arrive during the night, can quickly pile up. If serious problems or malfunctions arise, administrators need to be alerted at once – not just when they get to work in the morning and check their email. PRTG makes this possible by sending out a push notification or an SMS.
A sensor for monitoring your email
IMAP Sensor: PRTG’s IMAP Sensor comes with special filters and assigns statuses based on certain words or phrases found in emails. For example, PRTG can scan the subject or body of an email for keywords that are defined by you before the respective search.

How to use email monitoring to monitor applications and backups
In PRTG, add the IMAP Sensor to the device that represents your mail server, and make sure the application to be monitored is able to send status emails to the corresponding email address.
Specify the conditions for which you would like to receive an alarm. Two examples: if you have not received an email for 24 hours from your backup software, or if certain words such as “error” appear in an email.
Test your configuration by sending yourself an email with the words that you specified in your filter rules. More detailed instructions can be found here.
Mail server monitoring: All administrators should monitor the functionality of their mail servers. This means monitoring availability, performance, and the error-free delivery of emails.
Sensors for monitoring your
SMTP & IMAP Round Trip Sensor: This sensor uses SMTP and IMAP to monitor the end-to-end delivery of your email.
SMTP & POP3 Round Trip Sensor: This sensor uses SMTP and POP3 to monitor the end-to-end delivery of your email.
PRTG comes with several other sensors which use SNMP and other protocols to monitor your servers, thereby providing you with important hardware and performance data so you can eliminate downtime.

Using PRTG to ensure emails are delivered
PRTG delivers an email to the mail server (or an email client) via SMTP.
The SMTP server delivers the email to a POP3 server (which can be at another location, in the LAN, or on the same server).
PRTG checks for emails from the POP3 server every second until the test email arrives.
Practical tip: “Hey Gerald, what would you tell administrators who are looking to monitor their backups?”
“Sometimes it takes a little trial and error before the IMAP Sensor is best configured for your own particular situation. For the sake of simplicity, we recommend setting up a separate email account for each of your backup solutions or applications. You should also use separate mailboxes for your monitoring which cannot be accessed via a client or some other interface. By doing so, you can automatically rule out the sources of many errors, including the erroneous reading of the age of a message.
If the IMAP Sensor is still not working according to plan, verify the access data you entered is correct by ensuring that PRTG can log into the desired mailbox, and that emails are arriving there in the first place. Also check the limits of the IMAP Sensor, as these determine when an error or a warning status should be displayed.
The text filter you use to categorize incoming emails may also be a source of error. If you use regular expressions, in particular, be sure to check that their syntax allows for the desired text to be picked up by your filters. You can use a free Regex tool such as Regex101 or Regex Pal for this.”
