How can i troubleshoot why triggered alerts suddenly email not sending

[Olesya]

Hi there!

I'm a newbie in Splunk and faced with issues in triggered alerts that suddenly not send any more.

I had configured alerts and reports earlier and received alerts in the mail all the time.

I checked server settings, advanced setting in alerts,  run search index=_internal sendemail and find out that emails are sent but I don't receive them.

Does anyone have suggestions how to fix that?

 Any help that you can provide would be greatly appreciated.

If Splunk says it sent the alert then it's in the hands of the email system. Contact your mail admin for help finding what happened to the messages.

Hi @Olesya,

at first, check if the mail server is reachable by Splunk Search Head.

Ciao.
