MailNexus generates everything you need — install scripts, DNS records (SPF/DKIM/DMARC), SMTP credentials — for any Linux VPS. Pay per server. No subscription. No lock-in.
Ubuntu 20/22/24, Debian 11/12, Rocky 8/9, AlmaLinux 8/9, CentOS Stream 9 — script branches automatically.
A, MX, SPF, DKIM, DMARC records generated with the exact values your provider expects.
Hostname, user, password, ports 587 + 465. Built-in propagation + connectivity test.
One credit = one fully configured VPS. No subscriptions, no expirations.
Credentials never leave your browser. We don't store your VPS root password.
Submit this form and we'll set up your account with double the starter credits — enough to configure two production-ready SMTP servers on us. Tell us which plan you're interested in for when you're ready to scale.
