Upgrade Dovecot from 2.2.x to 2.3.x
Dovecot 2.3 breaks some backward compatible, and here's a short tutorial to convert your Dovecot 2.2 config file to fully work with Dovecot 2.3.
For more details, please read Dovecot wiki page: Upgrading Dovecot v2.2 to v2.3.
!!! attention
* 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
```
Upgrade Dovecot on Linux/FreeBSD/OpenBSD
Open a shell terminal, and switch to Dovecot configuration directory first:
- On Linux/OpenBSD:
cd /etc/dovecot/
- On FreeBSD:
- Please upgrade ports
mail/dovecot
andmail/dovecot-pigeonhole
first. You can use tool likeportmaster
orportupgrade
for this purpose. FYI: Using the Ports Collection - After upgraded both ports, please run:
- Please upgrade ports
cd /usr/local/etc/dovecot/
Run commands below as root user, these commands will:
