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-8.3 platform.

User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/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
First, fix an issue causing a segfault in the test suite by applying a sed:
sed -e "s;#include <unistd.h>;&\n#include <crypt.h>;" \
-i src/auth/mycrypt.c
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-2.3.2.1 \
--disable-static \
--with-systemdsystemunitdir=/lib/systemd/system &&
make
To test the results, issue make -k check. An error may be reported if Valgrind-3.13.0 is present when running the test.
Now, as the root user:
make install
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-systemdsystemunitdir=/lib/systemd/system:
This switch is used to set the correct installation directory for
systemd units.
--with-ldap: This switch enables
OpenLDAP authentication support.
--with-pgsql: This switch enables
PostgreSQL authentication support.
--with-mysql: This switch enables
MySQL authentication support.
--with-sqlite: This switch enables
SQLite authentication support.
--with-lucene: This switch enables
CLucene full text search support.
--with-krb5: This switch enables GSSAPI
authentication support.
Copy an example configuration, which you can use as a starting point:
cp -rv /usr/share/doc/dovecot-2.3.2.1/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.
