Before I go down the route of upgrading our main Solr instance from 6 to 7, just checking if anyone is using Solr 7 with Dovecot.
SOLR 7 works ok with dovecot. We did not upgrade but indexed from scratch with 7.0.0.
From our experience:
Make sure that you set the default queryResponseWriter to XML on solrconfig.xml:
<queryResponseWriter name="xml"
default="true"
class="solr.XMLResponseWriter" />Because the default response type is now JSON instead of XML and I don't think dovecot sends a wt=xml to make it explicit.
Also, consider going to 7.0.1 because 7.0.0 could not read indexes from 6.x versions. As I said we did a reindex so we were unharmed by that bug but just saw it on the 7.0.1 changelog.
