The task is to turn a freshly provisioned, dedicated machine (with its own public IP) into a secure, fully-featured Ubuntu hosting environment. I need Ubuntu installed, hardened, and then managed through Webmin/Virtualmin rather than cPanel or Plesk. The stack must comfortably run anything from plain HTML to PHP-driven WordPress and full e-commerce builds, so current versions of Apache or Nginx, multiple PHP versions, and MariaDB/MySQL are expected. Email has to be part of the same box. I am leaning toward a Roundcube or Cosmos webmail front-end, but I am open to a better suggestion if you can justify it. Under the hood, please wire up a solid Postfix/Dovecot combination with SPF, DKIM, and DMARC so outgoing mail lands in the inbox and not spam. Deliverables • Latest LTS Ubuntu installed, updated, and secured (UFW and basic hardening) • Webmin/Virtualmin configured over HTTPS, ready for virtual-host creation • Web stack (Apache or Nginx, PHP-FPM, MariaDB/MySQL) tuned for performance • Let’s Encrypt SSL auto-renewal for all future domains • Email server set up with SMTP, IMAP/POP3, Roundcube or Cosmos (or your proposed alternative) plus SPF, DKIM, DMARC records tested • SFTP access, fail2ban, and automated off-site backups configured • Clear handover notes covering every major step, admin passwords, and DNS entries to add on my registrar side I already have the dedicated IP; let me know if any additional tools or licenses would make the build smarter or more secure. Once everything passes basic uptime and send/receive tests, the job is complete.
