The PowerMTA 6.0r3 Auto Installer runs as a single script and installs PowerMTA 6.0r3 from a .deb or .rpm package, asks you for your domains, IPs and rotation, then generates every authentication record your domains need and publishes it to your DNS. Bash and Python installers both included — no config files to hand-edit, no half-configured signing.

PowerMTA is the commercial MTA that email service providers and high-volume senders run when delivery actually matters. The 6.0 series is the current generation, and 6.0r3 is the release this installer targets.
A single PowerMTA instance delivers in parallel across many IP addresses and splits traffic into independent streams called virtual MTAs. Each stream carries its own IPs, its own reputation and its own rate limits, so transactional mail, marketing campaigns and per-customer sending never interfere with each other.
Settings cascade from global to provider, domain, IP and pool level. That is what lets you honour Gmail's limits, Microsoft's limits and Yahoo's limits at the same time from one box — and it is exactly the layer the auto installer pre-configures for you.
Per-message transaction data, automatic back-off and IP warm-up support mean you can see why a message failed and react to it, instead of watching an opaque queue grow.
Licence included: Your PowerMTA 6.0r3 licence is applied automatically by us during installation and managed by us from there on. Nothing to buy separately and no licence key for you to supply.
Every record below is produced from the configuration the installer just applied. Add a Cloudflare, GoDaddy or Namecheap API key and they are written straight into your zone, with existing records detected and merged rather than duplicated. Prefer to do it yourself? The installer hands you every record at the end for manual entry.
Declares which IP addresses are allowed to send mail for your domain. The installer reads the sending IPs it just configured in PowerMTA and writes them straight into your SPF record.
TXT @ v=spf1 ip4:YOUR.SENDING.IP -allCryptographically signs every outgoing message so mailbox providers can verify the body and headers were not altered in transit. Keys are generated on your server and never leave it.
TXT sel1._domainkey v=DKIM1; k=rsa; p=MIIBIjANBgkq...Tells mailbox providers what to do when SPF or DKIM alignment fails, and gives you aggregate reporting on everything sent in your name. Required by Google and Yahoo for bulk senders.
TXT _dmarc v=DMARC1; p=reject; rua=mailto:dmarc@yourdomain.comARC preserves the original authentication result when a message is forwarded or passes through a mailing list — the situation where plain SPF and DKIM normally break and legitimate mail starts bouncing.
ARC-Seal · ARC-Message-Signature · ARC-Authentication-ResultsBIMI puts your verified logo next to your messages in the inbox. It only takes effect once DMARC is at enforcement, which is exactly the state the installer leaves your domain in.
TXT default._bimi v=BIMI1; l=https://…/logo.svg; a=https://…/vmc.pemARC fixes the oldest hole in email authentication: forwarding. When a recipient auto-forwards your message or it passes through a mailing list, the sending IP changes and SPF fails. ARC (RFC 8617) seals the original result into the message so the final destination can still trust it.
BIMI is the reward for getting the rest right. Once DMARC is at p=quarantine or p=reject, a published BIMI record lets mailbox providers show your verified logo next to every message in the inbox.
Inbox placement is not a single switch. It is authentication, identity, infrastructure hygiene and rate discipline all pointing the same way. The installer sets up all four before you send your first message.
Google and Yahoo require SPF, DKIM and DMARC from bulk senders. A server that ships with all three aligned — plus ARC and BIMI — starts from a trusted baseline instead of fighting the spam folder.
Forward and reverse DNS, the HELO hostname and the envelope domain are all lined up. Mismatched PTR records are one of the fastest ways to get throttled by large mailbox providers.
With DMARC at enforcement and BIMI published, your logo can appear beside your messages. Recipients recognise the sender before they read the subject line, which lifts opens and lowers complaints.
ARC sealing carries the original authentication result through forwarders and mailing lists, so mail that used to fail SPF after a redirect still authenticates at the destination.
Virtual MTAs, IP pools and per-domain queue settings are configured so each mailbox provider is sent to within its own limits, with automatic back-off when a provider pushes back.
The PowerMTA web monitor, accounting logs and bounce categorisation are switched on and secured, so you can see queues, throughput and rejections instead of guessing.
Authentication and configuration get you delivered. Staying in the inbox after that still depends on list quality, sending consistency and engagement — we set the foundation and tell you honestly what you need to keep doing.
Two package formats cover every supported distribution. You get both with your purchase, so moving from Ubuntu to Rocky Linux later does not mean buying again.
Installed with dpkg -i or apt install. Uses APT for dependency resolution and systemd for service management.
Installed with rpm -ivh or dnf install. Uses DNF/YUM for dependency resolution and systemd for service management.
64-bit (x86_64) Linux, root or sudo access, and a clean server are recommended. Not sure which family your server belongs to? Run cat /etc/os-release and send us the output.
From payment to a verified, inbox-ready sending server.
Pay the one-time $499 fee in Bitcoin, Litecoin, USDT or any other supported coin. Your account is created at checkout with the email and password you choose.
You receive both scripts: a bash installer to run directly on the server, and a Python installer to run remotely from your own machine over SSH. Use whichever suits you.
The installer asks you everything it needs as it goes — sending domains, IP rotation, virtual MTAs and pools, hostname, and your DNS provider API key if you want records applied for you.
Add a Cloudflare, GoDaddy or Namecheap API key and SPF, DKIM, DMARC, ARC and BIMI are written straight to your zone. Skip it and the installer prints every record at the end for manual entry in any DNS panel.
PowerMTA 6.0r3 is installed and running with the web monitor up, authentication in place, and a test send to confirm every check passes.
A single one-time payment. No subscription, no per-domain fee, no monthly renewal.

Everything buyers ask before ordering the installer.
Yes. The licence is applied automatically by us during installation and managed by us afterwards. You do not need to buy a licence separately or supply a licence key — the $499 covers the licence, the automated installation, the configuration and the full DNS authentication setup.
Use the .deb package on Ubuntu 20.04, 22.04 and 24.04 LTS. Use the .rpm package on Rocky Linux 8/9, AlmaLinux 8/9 and CentOS Stream 8/9 or CentOS 7. Both packages ship with the purchase, so you can move between distribution families later without buying again.
ARC keeps your authentication result intact when a message is forwarded or relayed through a mailing list. Without ARC, forwarding rewrites the path and SPF fails, so legitimate mail gets rejected or filed as spam. With ARC sealing enabled, the receiving side can still see that the message passed authentication at the original hop.
The installer publishes a valid BIMI record and validates your SVG Tiny PS logo. Displaying the logo is then up to each mailbox provider: Gmail requires DMARC at enforcement plus a Verified Mark Certificate issued by a certification authority. We wire the VMC reference in as soon as you supply one.
No. Adding a Cloudflare, GoDaddy or Namecheap API key is optional and only enables automatic DNS. With a key, the installer detects existing records, avoids duplicates and writes SPF, DKIM, DMARC, ARC and BIMI in one pass. Without a key, it prints every record at the end so you can paste them into any DNS panel yourself.
You run it yourself — we never need access to your server. The bash script runs directly on the machine, and the Python script installs remotely over SSH from your own computer. Both are included, and both ask you for the settings they need as they go.
Your sending domains, hostname, the IPs to use and how you want them rotated, virtual MTA and pool layout, and optionally your DNS provider API key. It configures PowerMTA from your answers — there is no config file to hand-edit.
The install and configuration typically completes in well under an hour on a clean server. DNS propagation adds a short wait before every authentication check goes green.
Yes. Choco Mailer normally sells for $199 and is bundled at no extra cost with every PowerMTA 6.0r3 Auto Installer purchase. You pay $499 once and get both, a combined value of $698. We add Choco Mailer to your account after your payment is confirmed — there is nothing extra to buy or configure at checkout.
