Every build writes the exact source it was built from, uncommitted work and new files included, as source.tar.gz next to the app, named after that tree. Docker builds, which have no git, pack the build context and name it by a hash of its files. The sign-in page and Settings > About link to it instead of a repository that can drift. What users, operators and packagers see no longer names the upstream server: - interface text, in all nine catalogues, with a token-session line for Security; - server messages; - the settings, now MAIL_SERVER_URL, MAIL_SERVERS_FILE, ADMIN_URL and MAIL_SERVER_FOLLOW_ADVERTISED_URLS, and mail-servers.example.json; - the Tenants notice, which is gone; - the README, CONTRIBUTING and SECURITY. ihasmail's own FEATURES, KNOWN-ISSUES and ROADMAP stay with public ihasmail, and INBUXA.md is folded into the README.
