I have email in IMAP server with .csv attachment and i am trying to index the attachment. this csv file contains specific set of data. This works for .xml files attached. But not for .csv files attached. so far i was able to get body of the email only.
I believe this was brought up in question: https://answers.splunk.com/answers/222827/does-imap-mailbox-support-indexing-of-attachments.html
