Mailpopbox
Email privacy through anonymity.
Wildcard Addresses
Mailpopbox is not a typical mail-server: it is meant to be used by a single person. All messages
addressed to any mailbox at the configured domain are delivered into a single account. This lets you
create site-specific email addresses, allowing you to segment or compartmentalize your emails. Any
time a form or a person asks for an email address, you can simply make up a
RandomAccount@yourdomain.net. This enhances your privacy by:
- Not revealing your main email address to organizations.
- Giving you more control over blocking email messages, because you can filter on the To address.
- Determining when one organization has given their email list to another, since you can give each
organization a unique account.
- Prevent organizations from cross-referencing account information by email address.
- Offer minor protection in the event of a data breach, because your accounts can each have unique
email addresses.
Reply Controls
While many domain registrars offer the above wildcard forwarding, none offer the ability to reply
from the random addresses that a message gets sent to. But Mailpopbox does! By default, mail gets
sent as the mailbox@yourdomain.net address, but if you add a [sendas:ACCOUNT] tag to the
Subject line of any message, Mailpopbox will rewrite the From address to be
ACCOUNT@yourdomain.net.
