Problem with SMTP Settings in Openmanage Enterprise

Hello,

we are using OpenManage Enterprise Appliance with Version Version 3.7.0 (Build 82).

I tried to configure the smtp settings but allways get the message "test mail could not be send".
The communication to our Exchange is working, i can see that in the Exchange Logs. 

So DNS, Firewall rules, ... are ok.

Our Exchange Connectore needs a TLS connection and we use on this connector a certifiate from our internal Windows CA. I use the "use SSL" option in the STMP Settings but still get no valid connection to the exchange.

The Error Message is:

Sending certificate Subject Issuer name Serial number Thumbprint Not before Not after Subject alternate names
TLS negotiation failed with error CertUnknown

We have some Dell PowerEdge Servers with IDRAC and they working without any Problem. The config is the same.

It would be greate if someone can help me.

Thanks and best regards,

    Skttec,

     

    Many mail server configurations won't send as a https://dell.to/3nTBV0o email, so it may just be an issue around the test feature. What I would suggest is going to the servers iDrac and then run the Test Event from there, selecting a critical one such as CPU002.
    Now if that fails, what I would suggest is to scrap the existing configuration and then just config server to send snmp to OM Ent and then set OM Ent to email alerts and then try the test again.
    Let me know if this helps.

    Hello Chris,

    it doesnt work with the triggered snmp error.

    I got the same error on the exchange server.

    if i run a smtp test on the idrac itself its working fine, but idrac uses StartTLS and not SSL. If i change it to SSL its not working anymore on the idrac too.

    On the Openmanage i can only select SSL, is it possible to use StartTLS?

    If i dont use SSL on the Openmanage und use a smpt connector on the exchange without tls its working too. But we need a TLS connection, because we dont want a unsecure connection.

    Dmitry12234,

     

    The issue you're seeing is due to the test button in the tool, which can be problematic. What I suggest is to test by firing it from the servers iDrac, and not the OM Ent tool. 

     

    Let me know how it goes.

    Hello, 

    We are having the same issue. In order for the the Dell OME Services plug-in to work correctly and create support cases we need the SMTP server on the OME appliance to use STARTTLS as it is connection encyrption type. Not TLS or SSL. 

    When will Dell make a change to allow STARTTLS as the connection encryption on the OME appliance as it does the idracs?

    Hello rbrown0214

     

    Typically Services Plugin/Secure Connect Gateway should be able to email you from Dell's SMTP server if you configure nothing.

     

    What mail server do you use? 

     

    All the main online solutions work even O365 and nothing else has made this requirement for STARTTLS.

     

    It was advised if it does not work for you to call into support and open a support case and an engineer can do a remote session with you to get a look.

    We aren't using the services connect gateway.

    We use Amazon SES SMTP

    Thank you.

    Hello rbrown0214,

     

    Can you send an image that shows your whole configuration not just the SSL check box please?

    Hello rbrown0214,

     

    Have you tried check the SSL box and use port 587?

    To set up a STARTTLS connection, the SMTP client connects to the Amazon SES SMTP endpoint on port 25, 587, or 2587,
