POP3 Round Trip

Hello,

I would like to create a Round Trip sensor in order to test if i can send an email (it is the better test to see if my Exchange server works or not).

But with POP3 or IMAP with this sensor i have an error message:

"Connection to SMTP Server: Error establishing secure connection ([TLS10-12] Socket Error # 10060 Connection timed out. [TLS10] Socket Error # 10060 Connection timed out. [SSL30] Socket Error # 10060 Connection timed out. [SSL20] Socket Error # 10060 Connection timed out.)"

It is strange because i wrote my own email address in "from" and "to" and it works normally.

I have differents sensors to supervise my Exchange server so SNMP should work.

Maybe that it comes from "Helo Ident", i wrote my domain name here.

I tried searching solutions in this forum but i still can not solve my problem, sorry if you have already answered.

Thank you in advance.

Dear Stagiaire2

Please clarify: Do you think SNMP should work, or that SMTP should work?

Do you have any other working SMTP sensor to this device? Does the Exchange server / firewall allow the PRTG host SMTP relay?

Hi,

In my Exchange i have lot of sensors like "Sensor Retry Mailbox Delivery Queue Length _total" or "Sensor POP3" or "Sensor SMTP" so for me SMTP is working in this device.

I will check with my boss if our firewall allow the PRTG host SMTP relay next week.

My problem is resolved, in fact in my architecture i have one physical server and 2 virtuals servers inside.

And even if i have an MSExchangeIS sensor in a virtual server i have to choose the second one to apply the Round Trip sensor.

So it was not the firewall.

Thank you anyway for your time,

Stagiaire2.
