Postfix gives unsupported dictionary type: btree on Leap 15.3

18 Jan 2022

      I have a recent installed Leap 15.3 system on a Raspberry Pi 4B and I try to 
configure it as an email server.

The access port 25 should offer STARTTLS, which has been configured as well.
This requires also the parameter smtpd_tls_session_cache_database = btree:/
var/lib/postfix/smtpd_tls_session_cache

However when I access using STARTTLS to port 25 I get the warning:
postfix/tlsmgr[13932]: warning: btree:/var/lib/postfix/smtpd_tls_session_cache 
is unavailable. unsupported dictionary type: btree

I do see the file /var/lib/postfix/smtpd_tls_session_cache.db

Should I file a bug report?
