Today&rsquo;s PR #2598 closes that gap: <strong><code>skymail-bridge</code></strong> — a sender-side SMTP bridge that lets an operator send email to and receive email from a Skywire identity, using the same Postfix machinery they already run.</p> <h3 id="the-address-shape">The address shape</h3> <p>A Skywire identity is a 33-byte compressed secp256k1 public key. Base32-encoded (RFC 4648), that&rsquo;s 52 characters — small enough to fit inside RFC 1035&rsquo;s 63-octet DNS label limit, which is the hard constraint email addresses have to live within. Hex would be 66 characters and break.</p>
