I need a complete web-based mail solution deployed on my Linux VPS. The finished system must let me and future users send and receive messages through IMAP, POP3 and SMTP while staying fully secure behind SSL/TLS encryption, solid spam filtering and reliable user authentication. I am comfortable with a proven open-source stack—Roundcube, RainLoop or something comparable—so long as it installs cleanly, runs smoothly on a LAMP/LNMP environment and can scale to several domains. You will handle everything: package installation, database configuration, virtual domain mapping, DNS/MX guidance and the final hardening steps. Deliverables • Fully functional webmail interface running on my server • IMAP, POP3, SMTP services configured and tested • SSL/TLS certificates installed (Let’s Encrypt is fine) • Spam filtering and user auth in place and verified • A brief hand-off document covering daily administration, backups and updates I’ll supply root SSH access and any DNS credentials you need. Once your test messages flow in both directions without errors and all security checks pass, the job is done.
