* fix: Conditionally add service state These services will no longer copy over state unless they are enabled. The biggest offender here was ClamAV as it's database that is baked into the docker image is over 200MB and would copy over to every container instance with a volume mounted state directory. * chore: Add Dovecot to conditional support
