...from where the compiled Solr plugin was to this directory: ln -s /usr/local/lib/dovecot/lib21_fts_solr_plugin.so And now I have the following error: dlopen(/usr/lib64/dovecot/modules/imap/lib21_fts_solr_plugin.so) failed: /usr/lib64/dovecot/modules/imap/lib21_fts_solr_plugin.so: undefined symbol: mailbox_get_virtual_box_patterns Couldn't load required plugins Error: imap dump-capability process returned 89 Fatal: Invalid configuration in /etc/dovecot/dovecot.conf I'm missing some steps in this installation for sure, do anyone have any clue?
