I am using the ELK stack to analyze a mailbox, I want to ingest a mailbox.To do this I want to use the .pst file from said mailbox, but I don’t see the exact way to do it.Some help? Searching I found the following example.

input {
  file {
    path => "/path/to/output_directory/*.eml"
    start_position => "beginning"
    sincedb_path => "/dev/null"
    codec => "plain"
  }
}

filter {
  What filters are recommended to avoid leaving me information?
}

output {
  elasticsearch {
    hosts => ["http://localhost:9200"]
    index => "emails"
  }
}
