Hi all, I have started work on an ElasticSearch FTS plugin for Dovecot.
It's available now on GitHub at: https://github.com/ascendantcom/fts-elasticsearch Please note that it is still in heavy development right now. It supports indexing, searching and expunging with some caveats (no multi-mailbox search or attachments). Pull requests, suggestions and bug reports very welcome! Cheers, Josh
