Allowing or Blocking Senders

To ensure emails from people you trust always reach your inbox, add them to your allow list:

1. Visit quarantine.thexyz.com
2. Log in using your email address and one-time link
3. Navigate to Sender Allow List
4. Enter the sender's address (e.g. [email protected]) or domain (e.g. example.com)
5. Click save

You can choose whether to match by envelope sender, header sender, or both.

If you’re receiving unwanted mail, you can block senders entirely:

• Block a specific address: [email protected]
• Block an entire domain: badsite.com
• Block by TLD: *.ru, *.cn, etc.

Blocked senders are rejected before quarantine — you’ll never see them again.

Use * to match groups of senders:

• *.nl — block or allow all from the Netherlands TLD
• example.com — allow or block everyone at that domain
• marketing@* — match all marketing emails from any domain
