Hello, I have Dovecot configured with Solr for the indexes.

I have need your support for upgrade solr 7.7.2 to 8.4.1. Solr 7.7.2 has a security issue CVE-2019-12409.

It's possible upgrade of Solr? Dovecot work correctly with Solr 8.x?

The Solr documentation recommended after updating: "It is always strongly recommended that you fully reindex your documents after a major version upgrade."

There are tips for Dovecot?

Easy mitigation - block or control all access on port 18983 via iptables ? Might be a bit of a blanket statement though ...

Be aware than later version of Solr use a *lot* more ram. I tested last year with 8.3.0 and even with tuning was seeing a much higher higher RES memory usage.
