The running mailserver was DMS v15.1.0 (Dovecot 2.3); docker.io:latest now maps locally to v16.0.0 (Dovecot 2.4), whose parser rejects the repo dovecot.cf shared namespace ('namespace { } is missing section name') — recreating the container on :latest crash-looped dovecot (exit 89). Pin to docker.io/mailserver/docker-mailserver:v15.1.0 (the locally present v15 build, id 4f5093c). A deliberate v16 upgrade needs a dovecot.cf migration first (separate task). POSTFIX_MESSAGE_SIZE_LIMIT (from the earlier #101 commit) is supported by v15 and verified (quota_max_mail_size = 200M).
