I wanted to know where is this property defined so I can go make changes to it. I know that the issue is a firewall not allowing the traffic to go through (for which I've taken the necessary steps internally). 

Also, how come it's not showing on any of my other agent collectors?

Hi Manish,

The package com.timestock.tess indicates this is coming from CEM

The CEM "Email Settings" page has the SMTP settings and "Exception occurred while testing email settings" implies this is for when using the "Test Connection" option on that page.

However I would expect "Test Connection" error in MOM log only, so not sure why you are  seeing it in 2 Collector logs instead.

CEM "Incident settings" also has "Incident Email Settings" which would get logged in EM running TIM Collection Service log at least, but they would not be for the testing scenario "Exception occurred while testing email settings".

Anyway if you login to your MOM CEM page you can check the  "Email Settings".

Hope that helps.

Regards,

Lynn

Lynn,

I am seeing these logs under other collectors also and not just 2 I mentioned earlier.

So I found the setting.....

CEM GUI -> System -> Email Settings Tab.

I'll have to submit an internal firewall request to allow this comm.

Thanks Lynn_Williams for helping out.

Lynn_Williams

so the firewall rule should only be allowing for connection from MoM server to the dmzsmtprelay.xx.xxxxxxxx.com on port 25, right? Not from every Collector to dmzsmtprelay.xx.xxxxxxxx.com on port 25, rigth?

Hi Manish,

If your CEM Incidents are configured to send emails then I think both MOM and EM running TCS would need the firewall open for your dmzsmtprelay.xx.xxxxxxxxxx.com on port 25.

Regards,

Lynn

Dear Manish:

Did Lynn's post answer your question? Please post any followup questions or mark as correct  if helpful. Seems that your SMTP relay may be down . Your CEM box syslog and the SMTP Relay's syslog may help in telling you if the relay is busy or not working

Thanks

Hal

Hal,

I'll take a look at CEM settings and provide feedback
