PT Scandium · Element 21 · Jakarta, Indonesia
PT Scandium is a software product company in Jakarta, founded in 2006 and led by Edison Chindrawaly — in professional software engineering practice continuously since December 2002. We build and sell our own software, and we run it ourselves before we ask anyone else to.
Engineering since Dec 2002 Founded Feb 2006 Jakarta, Indonesia
The firm
We are engineers who have kept production systems alive for two decades. Everything we sell is written, run and supported by the same people — nothing is subcontracted, and nothing ships that we would not put on our own servers.
How we build
Scandium builds and sells its own software. We do not take project work, and we do not run your systems for you — we ship products you install, operate and keep. Two decades of running production systems decided how they are built.
Our software runs on your server, inside your network. There is no tenant, no console we log into, and no dependency on us staying online for your systems to work.
We sit above software you already trust and write the configuration it already reads. Nothing is locked in a proprietary format, and removing our product leaves a working system behind.
State lives in a database you can back up, query, replicate and audit yourself. No opaque store, no export ticket, no format that needs us to read it.
Compiled Go, copied to the server, started by systemd. No interpreter to patch, no dependency tree to resolve, no container stack to keep alive underneath it.
Anything our software claims to have configured, it checks against reality on a schedule and reports back. Green means it was queried and confirmed, not that a file was written.
Security updates reach every plan, including the free one. We have kept systems running for two decades and we do not expect a product to be rewritten every eighteen months.
Products
Every Scandium product starts as something our own engineers needed and now depend on. GU.Email is the first we have released — the control layer for a self-hosted mail server.
Product · available now
One Go binary that configures, verifies and watches Postfix, Dovecot and Rspamd — so DKIM, SPF and DMARC stop being something you hope you got right.
Why GU.Email exists
Every self-hosted mail stack is three daemons, four config dialects and a set of DNS records that quietly drift out of date. Nothing crashes. Mail just stops arriving. We hit this on our own infrastructure and on clients' — often enough to build the fix.
Three daemons, one truth. Postfix, Dovecot and Rspamd each keep their own idea of your domains, users and policies. Keeping them in agreement is manual work nobody schedules.
DNS that was right last quarter. A rotated DKIM key, a moved relay, an SPF record that quietly exceeded ten lookups. All valid syntax. All silently rejected.
Deliverability found out by customer. The first alert most teams get is a client asking why they never received the invoice. By then the reputation damage is already done.
The product — GU.Email
GU.Email sits above the stack you already trust. It writes the configuration, generates the keys, publishes what belongs in DNS, and then keeps checking that reality still matches.
Copy a static Go binary to the server, drop in a systemd unit, done. No Node, no Ruby, no interpreter to patch, no container stack to babysit.
Domains, mailboxes, aliases, quotas, forwarding and TLS from one web interface — written out as the configuration those daemons already read.
GU.Email creates the keys, writes the records for you to publish, then queries live DNS and tells you which ones actually resolve. Green means verified, not assumed.
Scoring, greylisting and policy managed from the same screen as everything else — instead of a second admin panel with its own login and its own conventions.
Every domain, mailbox, key and check lives in a database you can back up, query, replicate and audit. Your data stays in a format you already know how to operate.
DNS records, certificate expiry and daemon health are re-checked on a schedule. GU.Email tells you something drifted before a customer does.
How it works
GU.Email doesn't replace your mail stack or hide it. It installs alongside it, and everything it configures stays readable, standard and yours.
One file, one systemd unit, one PostgreSQL connection string. It runs its own migrations on first start.
The Postfix and Dovecot configuration is written for you, a DKIM key pair generated, and your SPF and DMARC policy prepared.
Paste them at your DNS provider. They are queried back until every record resolves exactly as it should.
Mailboxes, aliases, spam policy, certificates and health checks — all in the same interface, for as long as the server lives.

Prices are in Indonesian Rupiah — we are based in Indonesia, so Rupiah is the price and the US Dollar figure below it is a courtesy conversion. Paid plans are billed once per year and include updates and support for the full term.
One domain, a handful of people, and no budget line for mail yet.

The company
Scandium is rare, light and stubbornly heat-resistant. It's the filament that keeps stadium lamps burning through a full match, and part of the alloy that lets a fighter airframe survive the temperatures of flight.
We chose the name because that's the standard we hold our software to: uncommon, durable, and still running long after the launch is forgotten.
Scandium is led by Edison Chindrawaly, who read Computer Science at the University of North Texas in Denton and graduated in 2002. He has worked as a professional software engineer and solution provider continuously since December 2002 — first in industry, then at the head of his own firm — and still reviews the architecture of everything that leaves here.
He incorporated PT Scandium in Jakarta on 8 February 2006. For nearly two decades the firm built and operated production systems across manufacturing, retail, photo studios, telecommunications, mining and logistics — the experience that now decides what we ship and how it behaves under load.
Today Scandium is a product company: we build and sell our own software rather than take project work. GU.Email is that same discipline, packaged. Two decades of running production systems taught us exactly which piece of infrastructure quietly breaks first — and email was always near the top of the list.
Questions
Yes — free forever, not a trial that expires. It covers one mail domain, three mailboxes and two aliases per mailbox, and it keeps receiving security updates at no charge plus one feature release a year. No payment details are needed to start.
A twelve-month licence for GU.Email, including the software itself, every update released during the term, and support at the level of your plan. The licence is delivered by email with your download and activation key.
No. GU.Email runs on your server, under your control. We never see, store or route your mail. That's the point — you keep the infrastructure, we make it manageable.
They need to be installed, and they are detected on first start. If you're beginning from a bare server, the SMB plan includes guided setup so your first domain goes live correctly.
Your mail server keeps running — GU.Email never holds your email hostage. You stop receiving updates and priority support until the licence is renewed.
No. Scandium builds and sells its own software products only — we do not take contract, consulting or bespoke development work. GU.Email is our first released product. If you need more than the SMB plan covers, and we will quote for your deployment.
Through Xendit, Indonesia's licensed payment gateway. Credit and debit cards, bank transfer via virtual account, QRIS and major e-wallets are accepted. Prices are charged in Indonesian Rupiah; the USD figure on each plan is an approximate conversion.
No — all purchases are final and licence fees are non-refundable. That is why the Startup plan is free and permanent rather than a trial: run GU.Email on your own server, for as long as you like, and satisfy yourself before you pay. Billing errors and undelivered licences are always put right. See our refund policy.
Yes. Every purchase receives a proper invoice, and Indonesian customers can request a faktur pajak. If your company needs to be invoiced against a purchase order, write to us and we will arrange it.
By email, at the address below. Startup is answered on a best-effort basis and SMB within one business day. Business hours are Jakarta time, Monday to Friday.
Get started
Tell us how many domains and mailboxes you run, and we'll send a licence, an invoice and a payment link the same business day. Bigger than the SMB plan? Say so and we'll quote for it.
