Dovecot 2.3 uses TLSv1 as minimal SSL protocol, if you prefer TLSv1.1 or
TLSv1.2, please set the protocol version in parameter `ssl_min_protocol`
like below:
* Currently only FreeBSD offers Dovecot 2.3 by the ports tree, other Linux
or OpenBSD distributions still offers Dovecot 2.2, you should stick to
Dovecot 2.2 if your Linux/BSD vendor doesn't offer 2.3 yet.
* Dovecot 2.3 uses TLSv1 as minimal SSL protocol, if you prefer TLSv1.1 or
TLSv1.2, please set the protocol version in parameter `ssl_min_protocol`
like below:
```
ssl_min_protocol = TLSv1.2
```
```
ssl_min_protocol = TLSv1.2
```
