Hi

Currently gmail don't allow use smtp server as earlier. Instead it wants to use more secure authentication. For that reason the old way is not working anymore with Splunk. Fortunately they have implemented 2-factor authentication and additional app password feature which you could use.

Here is steps to do it

  1. https://support.google.com/accounts/answer/185833?sjid=13755993998155727325-EU#:~:text=to%2520your%2...
    1. Check above instructions and ensure that you have 2-step verification on (probably this is as Google has enabled it for all)
    2. Create a new app password for your Splunk server
    3. Login to your local splunk instance
        1. Settings -> Server settings
        2. Email settings
          1. Mail host: smtp.gmail.com:587
          2. Email security: Enable TLS
          3. Username: Your Gmail account where you have enabled 2 Step verification
          4. Password: App password for above Gmail account
          5. Allowed Domains: <add what is needed>
          6. Save
        3. Go to search GUI:

 

index=_internal
| head 1
| sendemail to="<your test email recipient>" subject=test sendresults=true format=table sendcsv=false
