After the install and configuration of IMAP Mailbox app, it's not indexing any email. I was successful at getting this working in our lab environment, but not our production splunk environment.
Splunk is being run as root, so this shouldn't be a permission issue. I was able to run the debug command and it successfully returns mail in our production system.
/opt/splunk/bin/splunk cmd python /opt/splunk/etc/apps/IMAPmailbox/bin/get_imap_email.py --debug
What could I be missing? Does anyone know of any other troubleshooting steps to resolve this issue?
Yes it does. You will need to install the app on the search head. This will let you "see" the app in your splunk web. But you should not be running your input on this box at all. There is no index for it to save to. This could be your problem.
The README file has instructions for a distributed setup. There is a TA app loaded with this app. You will need to install that TA on the indexer. This is where your input will execute the get_imap_email.py script and thus be able to save it to your indexer.
I hope that helps.
