Postfix, berkeley db support for tls caching
The berkeley db support: 'btree' missing for postfix tls
btree support are needed by postfix to support tls caching. The others database type come from installation not allows this capability:
postconf -m|xargs cidr environ fail inline internal lmdb memcache mysql pipemap proxy randmap regexp socketmap static tcp texthash unionmap unix
The tls caching are required by tls support and delivery error message in logs if missing.
If you plan to use SSL/TLS authentification with postfix, I do not found an alternative solution to have tls caching and stop error messages.
Test in alpine 3.14/edge
