|
||
|
|
<p>For more details, please read Dovecot wiki page: <a href="https://wiki2.dovecot.org/Upgrading/2.3">Upgrading Dovecot v2.2 to v2.3</a>.</p>

<p>Dovecot 2.3 uses TLSv1 as minimal SSL protocol, if you prefer TLSv1.1 or
|
||
|
|
TLSv1.2, please set the protocol version in parameter <code>ssl_min_protocol</code>
|
||
|
|
like below:</p>
|
||
|
|
<p><code>ssl_min_protocol = TLSv1.2</code></p>
