Hello,
I have dovecot 2.3.17 running on FreeBSD 12.2 and it keeps panicking:

While reading about fts/fts_squat I came across the page noting it was
deprecated. I am running a mail server for myself, and have avoided installing
Solr this entire time, but I guess its time to upgrade.
In the mean time hopefully this core dump can help figure out what is going on.

This is because fts_squat is not calling fts_mail_user_init. This is a bug, just not sure if it is going to get fixed with fts_squat being deprecated, so it would be best to migrate to something newer, like fts_flatcurve. Aki
