For companies,
email is as important as ever. If you’re an IT administrator, it’s therefore vital that you monitor your email infrastructure (e.g., mail servers) around the clock and without interruption. PRTG comes with sensors for the major protocols used for sending and retrieving emails.

In particular, two main protocols are used to retrieve messages from an email client: the Post Office Protocol Version 3 (POP3) and the Internet Message Access Protocol (IMAP). The difference between these protocols? POP3 downloads messages from the mail server to the recipient's computer. As a result, the email is only available locally in the POP3 mailbox. IMAP, on the other hand, downloads a copy of the email to the recipient’s computer and leaves the original message on the server.

PRTG Network Monitor keeps a constant eye on SMTP and POP3 as well as SMTP and IMAP so you can rest assured that your emails are being sent and received properly.

Sensors for monitoring response and retrieval times


The SMTP&POP3 Round Trip  Sensor lets you monitor the sending and receiving of emails that originate in your system. It starts by sending an email to a given email address. This allows you to immediately see whether – and how fast – the email reaches the recipient, and how long it takes for the recipient to retrieve the email via POP3. If the delivery and retrieval are successful, then the email is automatically deleted.

If you simply wish to keep an eye on the response time of your mail server, then the POP3  Sensor is a good choice. The role of this sensor is twofold: it checks to make sure the corresponding threshold is not exceeded, and it sounds the alarm (via a notification) if a response time is too long compared to previous values.

 i What 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.

Monitor Microsoft Exchange Server
with PRTG

 


PRTG also comes with special sensors and a remote PowerShell feature for monitoring Exchange mailboxes. One such sensor, the Exchange Mail Queue (PowerShell) Sensor, monitors (among other things) the number of emails in the queue and the number of potentially malicious emails.

Meanwhile, the Exchange Mailbox (PowerShell) Sensor is crucial for ensuring the proper functioning of an Exchange Server. It shows you the number of emails in the monitored mailbox, the time of the last login, and the amount of memory being used by the mailbox on the server. A quick glance at the PRTG dashboard is therefore all it takes to determine whether the memory of a mailbox exceeds the defined limit.
