Dovecot-2.3.11.3
Introduction to Dovecot
Dovecot is an Internet Message
Access Protocol (IMAP) and Post Office Protocol (POP) server,
written primarily with security in mind. Dovecot aims to be lightweight, fast and easy
to set up as well as highly configurable and easily extensible with
plugins.
This package is known to build and work properly using an LFS-10.0
platform.

Installation of Dovecot
There should be dedicated users and groups for unprivileged Dovecot
processes and for processing users' logins. Issue the following
commands as the root user:
groupadd -g 42 dovecot &&
useradd -c "Dovecot unprivileged user" -d /dev/null -u 42 \
-g dovecot -s /bin/false dovecot &&
groupadd -g 43 dovenull &&
useradd -c "Dovecot login user" -d /dev/null -u 43 \
-g dovenull -s /bin/false dovenull
Install Dovecot by running the
following commands:
CFLAGS+=" -I/usr/include/tirpc" \
LDFLAGS+=" -ltirpc" \
./configure --prefix=/usr \
--sysconfdir=/etc \
--localstatedir=/var \
--docdir=/usr/share/doc/dovecot-2.3.11.3 \
--disable-static &&
make
To test the results, issue make -k
check.
Now, as the root user:
make install
Command Explanations
CFLAGS+=...LDFLAGS+=...: build
with libtirpc instead of the recently removed RPC code provided by
GlibC.
--disable-static: This
switch prevents installation of static versions of the libraries.
--with-ldap: This switch enables
OpenLDAP authentication support.
--with-pgsql: This switch enables
PostgreSQL database support.
--with-mysql: This switch enables
MySQL database support.
--with-sqlite: This switch enables
SQLite database support.
--with-lucene: This switch enables
CLucene full text search support.
--with-lua: This switch enables
Lua plugin support. This includes
a mail and push notification plugin.
Configuring Dovecot
Config Files
/etc/dovecot/dovecot.conf,
/etc/dovecot/conf.d/*, and
/etc/dovecot/local.conf
Configuration Information
Copy an example configuration, which you can use as a starting
point:
cp -rv /usr/share/doc/dovecot-2.3.11.3/example-config/* /etc/dovecot
The following configuration is a simple proof of concept with
IMAP service using local users for authentication and mailbox
location. Reading files from the conf.d directory is commented out since the
included example configuration requires OpenSSL and Linux
PAM.
sed -i '/^\!include / s/^/#/' /etc/dovecot/dovecot.conf &&
chmod -v 1777 /var/mail &&
cat > /etc/dovecot/local.conf << "EOF"
protocols = imap
ssl = no
# The next line is only needed if you have no IPv6 network interfaces
listen = *
mail_location = mbox:~/Mail:INBOX=/var/mail/%u
userdb {
driver = passwd
}
passdb {
driver = shadow
}
EOF
You will definitely want to read the official documentation at
http://wiki2.dovecot.org/ if you
plan to use Dovecot in
production environment.
