Multi Domain Linux Small-Business Mail Server

Job ID: 40383765

Budget: $250 – $750 USD

I need a complete, self-hosted email solution for a small business that I’ll be running on a Linux server (Ubuntu or CentOS—whichever you feel is best for the chosen stack). The key objective is to move away from third-party providers and gain full control over our mail, security, and data compliance.

The specific mail-transfer agent is still open: Postfix, Exim, Mailcow or another proven alternative can be used, as long as the end result is stable, secure, and straightforward to maintain.

What I expect from you:
• A production-ready mail server configured with SMTP, IMAP/POP3, spam and virus filtering, DKIM, SPF, DMARC, and valid SSL/TLS certificates.
• Simple webmail access and clear instructions so that I can add domains, users, and aliases without touching the command line every time.
• Written hand-off documentation covering major commands, config locations, and a basic backup/restore procedure.

If you have prior experience setting up reliable email systems for small businesses on Linux, I’d love to see your approach and timeline.
