Support Elasticsearch 5.0 readyness and keep elasticsearch imap importer free. Currently IMAP importer is only working with Elasticsearch 2 and it costs a lot of time and effort to update and maintain it for Elasticsearch 5. Donations welcome!

Import e-mails from IMAP (and POP3) into Elasticsearch 2.x
This importer connects to IMAP4 or POP3 servers, poll your mail and index it. The emails on the server will be never modified or removed from the server. The importer tracks (after the first initial full load) which mails are new or deleted and then only update the index for this mails.
Features:
- Incremental indexing of e-mails from a IMAP or POP3 server
- Support indexing of attachments
- Support for UTF-7 encoded e-mails (through jutf7)
- SSL, STARTTLS and SASL are supported (through JavaMail API)
- IMAP only: Folders which should be indexed can be specified with a regex pattern
- IMAP only: Subfolders can also be indexed (whole traversal of all folders)
- No special server capabilities needed
- Bulk indexing
- Works also with Gmail, iCloud, Yahoo, etc.
The importer acts as a disconnected client. This means that the importer is polling and for every indexing run a new server connection is opened and, after work is done, closed.
Prerequisites:- Java 7 or 8
- Elasticsearch 2.x
- At least one IMAP4 or POP3 server to connect to
Download .zip or .tar.gz from https://github.com/salyh/elasticsearch-river-imap/releases/latest (only Version 0.8.6 or higher) and unpack them somewhere.
Then run
bin/importer.sh [-e] <config-file>- -e: Start embedded elasticsearch node (only for testing !!)
- config-file: path to the json configuration file (see next chapter)
