Secure SMTP Server Setup

Job ID: 40269213

Budget: $30 – $250 USD

I need an SMTP server installed, configured, and fully secured so I can send only transactional emails such as order confirmations and password-reset links from my application. SSL/TLS encryption is mandatory; every connection to the server must negotiate a secure channel before any message is accepted.

I already have a VPS and a dedicated domain ready to point wherever you ask. Your work should cover the full chain of deliverability: installing the MTA (Postfix, Exim, or whichever stack you prefer), generating and applying SSL certificates, and setting up SPF, DKIM, and DMARC records so common providers do not flag the messages as spam. Once everything is in place, send a live test from a sandbox account and show the headers hitting inbox with a clean score.

Deliverables
• Working SMTP service reachable on the designated hostname and port
• Valid SSL/TLS certificate in place and auto-renewing
• DNS records (A, MX, SPF, DKIM, DMARC) verified as correct
• Brief hand-off document with the commands or UI path I would use to add future domains or rotate keys

If you normally lean on a control panel such as cPanel, Plesk, or even a Dockerised mail stack, feel free to propose it—what matters is stability, security, and simple maintenance.
