Familiar Addressing
Address a fax like an email: fax number at your gateway domain, with an optional display name mapped to the fax header.
Email-to-fax gateway
Send a Fax by Email — No Print Driver Required
The FaxFacts email-to-fax gateway lets anyone send a fax simply by emailing it — address the fax number like a recipient, attach the document, and the gateway converts and transmits it automatically.
Runs as its own secure SMTP service, with S/MIME, DKIM and TLS support, so inbound mail can be validated and protected before it ever reaches the fax engine.
No print driverFax straight from any email client.
S/MIME + DKIM + TLSVerified and encrypted inbound mail.

Core capabilities
Built to run as a secure, self-contained gateway.
This isn't an exhaustive list — if a workflow involves fax, ask us about it.
TLS
Encrypted Transport
STARTTLS on port 25, or an optional implicit-TLS listener on port 587, sharing the same certificate.
✓
Verified Senders
S/MIME signature verification and decryption, plus DKIM verification, with unsigned or unencrypted mail rejectable by policy.
⚑
Restrict & Validate
Allow or block by sender, IP address or recipient, with an optional password per sender or mailbox.

Custom Templates
Per-sender and per-domain templates control formatting, editable in GWMANAGER's tree view or a plain text editor.

Opt-Out Automation
A built-in script can add a sender's fax number to the global do-not-send list automatically.
How it works
From inbound email to a delivered, logged fax.
Every message is validated before it's ever converted or transmitted.
Email arrives
Inbound mail lands on the gateway's own SMTP service, or is fetched from an existing mailbox in POP3 mode.
Validated & decoded
S/MIME, DKIM and TLS checks run before the message is accepted; attachments and body content are parsed for conversion.
Converted to fax pages
Attachments convert automatically to fax pages using CopiaFacts Document Conversion, with the email body available as or alongside a cover sheet.
Transmitted & logged
The fax transmits through the standard CopiaFacts engine, with results written to the Windows Application Event Log.
Connect it to what you run
The gateway is a full CopiaFacts citizen, not a bolt-on.
Every inbound message converts to a standard CopiaFacts FS file, so the same engine logic applies to gateway mail as to any other fax job.
- Independent Windows service. CFGATEWAY runs separately from the main CopiaFacts engine, managed through GWMANAGER.
- Full CopiaFacts scripting. Arithmetic, branching, database access and external program calls are all available on every inbound message.
- Business system interfaces. Connects to Microsoft Exchange as an SMTP connector, and to SAP through fax SMTP addressing.
- Broadcast job launching. An email with an attached recipient list can launch a broadcast job directly into Job Administration.

Email-to-fax FAQ
Questions about the gateway.
How do I send a fax by email?
Address the message like an email, using the recipient's fax number in place of the mailbox name — for example, 16307416000@yourgateway.com. An optional display name can be included as well. Attach the document, and the gateway converts and transmits it automatically.
Can the gateway use our existing mailbox instead of its own domain?
Yes. In POP3 client mode, the gateway can fetch mail from a normal mailbox instead of running its own SMTP domain; the fax number is placed at the start of the subject line instead of the address.
Is inbound email verified and encrypted?
Yes. The gateway supports S/MIME signature verification and decryption, DKIM verification, and TLS on its SMTP listeners, and can be configured to reject mail that isn't signed or encrypted.
Can we restrict who is allowed to send faxes through the gateway?
Yes. Incoming mail can be validated by sender, IP address or recipient, with an optional password per sender or mailbox, and specific senders can be blocked outright.
Can the gateway launch a fax broadcast?
Yes. An email with an attached document and a recipient list can launch a broadcast job directly into CopiaFacts Job Administration.
Does the gateway integrate with Exchange or SAP?
Yes. It can run as an SMTP connector for Microsoft Exchange, and SAP can address faxes through the gateway using standard fax SMTP addressing.
