<p>All accounts come with limited cloud storage that <a href="https://kb.mailbox.org/display/MBOKBEN/Encrypt+files+on+your+Drive">can be encrypted</a>. Mailbox.org also offers the alias <a href="https://kb.mailbox.org/display/MBOKBEN/Ensuring+E-Mails+are+Sent+Securely">@secure.mailbox.org</a>, which enforces the TLS encryption on the connection between mail servers, otherwise the message will not be sent at all. Mailbox.org also supports <a href="https://en.wikipedia.org/wiki/Exchange_ActiveSync">Exchange ActiveSync</a> in addition to standard access protocols like IMAP and POP3.</p>

They have been in operation since <strong>2009</strong>. Posteo is based in <span class="flag-icon flag-icon-de"></span> Germany and has a free 14-day trial.

<h5>{% include badge.html color="warning" text="Domains and Aliases" %}</h5>
|

<p>Posteo does <a href="https://posteo.de/en/site/faq">not allow the use of custom domains</a>, however users may still make use of <a href="https://posteo.de/en/help/what-is-an-email-alias">subaddressing</a>.</p>
|
||||
|
||||
<h5>{% include badge.html color="warning" text="Payment Methods" %}</h5>
|
||||
<p>Posteo does not accept Bitcoin or other cryptocurrencies as a form of payment, however they do accept cash-by-mail. They also accept credit/debit cards, bank transfers, and PayPal, and remove PII (personally identifiable information) <a href="https://posteo.de/en/site/payment">that they receive</a> in connection with these payment methods.</p>
|
||||
|

<h5>{% include badge.html color="success" text="Account Security" %}</h5>
|

<p>Posteo supports <a href="https://posteo.de/en/help/what-is-two-factor-authentication-and-how-do-i-set-it-up">two factor authentication</a> for their webmail only. You can use either <a href="https://en.wikipedia.org/wiki/Time-based_One-time_Password_Algorithm">TOTP</a> a <a href="https://en.wikipedia.org/wiki/YubiKey">Yubikey</a> with TOTP. Web standards such as <a href="https://en.wikipedia.org/wiki/Universal_2nd_Factor">U2F</a> and <a href="https://en.wikipedia.org/wiki/WebAuthn">WebAuthn</a> are not yet supported.</p>
|
||||
|
||||
<h5>{% include badge.html color="warning" text="Data Security" %}</h5>
|
||||
<p>Posteo has <a href="https://posteo.de/en/site/encryption#cryptomailstorage">zero access encryption</a> for email storage. This means the messages stored in your account are only readable by you.</p>
|
||||
<p>Posteo also supports the encryption of your <a href="https://posteo.de/en/site/features#featuresaddressbook">address book contacts</a> and <a href="https://posteo.de/en/site/features#featurescalendar">calendars</a> at rest. However, Posteo still uses standard <a href="https://en.wikipedia.org/wiki/CalDAV">CalDAV</a> and <a href="https://en.wikipedia.org/wiki/CardDAV">CardDAV</a> for calendars and contacts. These protocols do not support <a href="https://en.wikipedia.org/wiki/End-to-end_encryption">E2EE (End-To-End Encryption)</a>. A <a href="/software/calendar-contacts/">standalone option</a> may be more appropiate.</p>
|
||||
|
||||
<h5>{% include badge.html color="success" text="Email Encryption" %}</h5>
|
||||
<p>Posteo has <a href="https://posteo.de/en/site/encryption#pgp_webmailer">integrated encryption</a> in their webmail, which simplifies sending messages to users with public OpenPGP keys. They also support the discovery of public keys via HTTP from their <a href="https://wiki.gnupg.org/WKD">Web Key Directory (WKD)</a>. This allows users outside of Posteo to find the OpenPGP keys of Posteo users easily, for cross-provider E2EE.</p>

<h5>{% include badge.html color="danger" text=".onion Service" %}</h5>
|
