Hi everyone!
My goal is to create an alert to monitor in ALL saved search if there's any email that no longer exist (mainly, colleagues that left the company or similar).
My idea was to search for the same patter of Mail Delivery Subsystem that happens when sending an email from Gmail (or any other) to a non-existing mail. Bud didn't find anything in _internal index, nor with a rest to saved search and index=mail is empty.
Amy idea?
Are you trying to find errors send email *from* Splunk or using Splunk to find any email sending errors? I'll assume the former for now.
Splunk logs email it sends in python.log. Searching for "sendemail" should find them. The only errors you're likely to find are failures to pass the email to the SMTP server. Any failures beyond that point would be sent as mailer-daemon messages to the sending mailbox. You'll only be able to search for those if you are Splunking the mailbox (not common).
