POP3 User Experience APM question

The description for this APM is as follows:

"This component monitor tests an email round trip from your SMTP mail server to your POP3 mail server and measures the time it takes to complete the trip."

I have this setup but I don't see where this completes a "round trip" As far as I can see this just tests outbound email to the POP3 account from our mail server. Where does the "round trip" take place? I assumed the complete scenario would also be coming back from the POP3 account to our Exchange server.

Would I need to setup another monitor but in reverse to achieve this?

POP3 User Experience Monitor sends e-mail through SMTP server and verifies that it gets delivered to POP3 server. That is the round trip documention talks about.

you can do something similar with Exchange by using MAPI User Experience Monitor, it sends email through SMTP server and verifies that it gets delivered to mail account on Exchange server.

Is this good enough or do you need something else?

HI sum--

I'll forward this to the APM writer to research and possibly update the doc.

Thats fine if that's what it does. I just wanted to make sure I wasn't missing something.

I can use the MAPI user experience to monitor the process coming back to our EX server.

thanks Martin.

One more question for you if I can Martin. I am looking into the MAPI Exchange UE and noticed this in another thread:

Sends an email to the user mailbox via SMTP. The email has a unique temporary subject name which starts with APM_prefix.
Connects to mailbox through MAPI, then searches the emails by Subject.
If the email it's looking for isn't found, it waits then searches again. It will stop when: 1) it's found, or 2) the timeout is reached, or 3) the maximum number of attempts has been reached.
Once the email is found, the monitor deletes it from the inbox.
The monitor collects the total round trip time for the email and compares it with your thresholds.
Once it knows the round trip time, status will be given according where it falls in your thresholds. If the email isn't found or SMTP or MAPI reported an error, APM will mark the monitor as down.

The emails that are being sent via the POP3 UE are similiar in that they start with the "APM" prefix. Is the POP3 UE APM supposed to delete these emails and process them the same as the MAPI UE APM? Or does the POP3 UE just access the mailbox and validate that the email made it based on the subject line and nothing more?

Appreciate the help.

POP3 User Experience Monitor behaves the same way like MAPI User Experience Monitor. It also deletes the message from POP3 server after it successfully confirms it was delivered.
