Greetings,

I am running Dovecot v. 2.2.13 on a Gentoo Box. Mail users are virtual, data for them is stored in a MySQL-DB, Sieve is enabled and deliver is the LDA in conjunction with Postfix.

This setup has been running for a few years now without problems, the configuration works.

Some weeks ago the setup was still on a Ubuntu 12.04 LTS box, and Dovecot was v. 2.0.9. I've installed a Tomcat there with Solr and configured the FTS-Solr plugin from Dovecot. Worked like a charm without any problems at all.

Now the same setup on the Gentoo box does not work at all; either indexer-worker does not find the directory or is just indexing 0 messages.

Solr is also installed again (v. 3.6.0) on Tomcat, and Solr is running properly. I checked it with my browser and the logs, they are showing no errors.

gentoo ~ # dovecot --version 2.2.13

So the question is: where's the error and how to fix it? I am kinda clueless right now.

Thanks in advance, Marc
