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.
