Hi all

I think I solved the problem by changing the treatment of plugins in the dovecot configuration. The global definition of the mail_plugins parameter was not being loaded within protocol sessions. I added the load in all the blocks where the sessions are defined. Now I ask, is it necessary to add in all sessions, better to say, the fts fts_solr plugins would not only be necessary in the imap protocol? This is a question to ensure less memory usage. Below is my current configuration:

Hi

I have a dovecot installed on debian 10 using solr to have a better search speed in emails. I am observing after an upgrade of the debian dovecot package the error below:
