More info
The local part is the recipient's fax number. The domain is fax.moarfax.com.
Every character that is not a digit is removed first. What remains must be 10 to 15 digits, and the domain must be fax.moarfax.com. A 10-digit number is accepted and sent as +1 followed by those digits. An 11-digit number that starts with 1 is sent as + followed by those digits. Every other accepted length is sent as + followed by the digits.
How it works
Five checks, then a confirmation email.
The sender must match

Secure your domain
Gmail and Google Workspace
Personal Gmail accounts are already signed by Google. Google Workspace on a custom domain needs an SPF TXT record of v=spf1 include:_spf.google.com ~all and the DKIM key from Google Admin.
Microsoft 365 and Outlook
Personal Outlook accounts are already authenticated. Microsoft 365 needs an SPF TXT record of v=spf1 include:spf.protection.outlook.com -all and the two DKIM CNAMEs from the Defender portal.
Your own mail server
Publish SPF or DKIM for the domain you send from. An SPF TXT record can list your mail server's IP. DKIM publishes the public key at {selector}._domainkey.
DMARC, if you want it
moarfax does not require DMARC. DMARC tells other receivers what to do when mail from your domain fails authentication. Start with v=DMARC1; p=none.
Check that it works
Send a test from your mailbox.
More info
Look for spf=pass and dkim=pass in a test email's Authentication-Results header, or use an external checker such as mail-tester.com. A rejection explains which check failed. Delivery time depends on the receiving machine.
If it fails
Email failed both SPF and DKIM authentication
