<p>Matched identities are used to select the correct (matched) identity when replying to a message.</p>
<p>Identities are as expected matched by account. For incoming messages the <em>to</em>, <em>cc</em>, <em>bcc</em>, <em>from</em> and <em>(X-)delivered/envelope/original-to</em> addresses will be checked (in this order) and for outgoing messages (drafts, outbox and sent) only the <em>from</em> addresses will be checked. Equal addresses have precedence over partially matching addresses, except for <em>delivered-to</em> addresses.</p>
<p>The matched address will be shown as <em>via</em> in the addresses section of received messages (between the message header and message text).</p>
<p>Note that identities need to be enabled to be able to be matched and that identities of other accounts will not be considered.</p>
