Build Instructions ------------------ For most people, the usual: ./configure make sudo make install is enough. This installs Dovecot under /usr/local. You must also rename the configuration file to get it to work: mv /usr/local/etc/dovecot-example.conf /usr/local/etc/dovecot.conf Read through it, make needed modifications and start dovecot binary. doc/configuration.txt tells you more about configuring Dovecot. SSL/TLS ------- Dovecot supports both GNUTLS and OpenSSL. Dovecot prefers GNUTLS if it's found, but fallbacks to OpenSSL. If you wish to force using OpenSSL, give --with-ssl=openssl to configure. For GNUTLS support you need version 0.5.5 or later. You can get GNUTLS from http://www.gnutls.org/ Optional Configure Options -------------------------- You can get a full list with: ./configure --help The options are listed like --with-thing or --enable-thing, usually they're also enabled by default. You can disable them with --without-thing or --disable-thing. Besides the standard options, Dovecot has added these: --enable-ipv6 Enable IPv6 support (default) Enable IPv6 support. By default it's enabled if system is detected to support it. --with-file-offset-size=BITS Specifies if we use 32bit or 64bit file offsets. 64bit is default if system supports it (Linux and Solaris does). You most likely won't have mails larger than 2GB, so you may want to drop this to 32bit for a bit smaller disk and memory usage. --with-mem-align=BYTES Specifies memory alignment, needed with many non-x86 systems and should speed up x86 systems too. Default is 8 with everyone to make sure 64bit memory accessing work. Currently it should also be safe to set to 4 when using 32bit file offets. With x86 it could be 1 as well if you want to save a bit of disk space (in .imap.index.data file) and memory. --with-rawlog Build support for logging user traffic When Dovecot is compiled with this option and user's home directory contains rawlog directory, all IMAP connections are logged into timstamp-pid.in and .out files. This is mostly useful for debugging. --enable-debug Enable some extra checks for debugging This is mostly useful for developers. It does quite a lot of unnecessary work but should catch some programming mistakes more quickly. --with-ssl=gnutls|openssl Build with GNUTLS (default) or OpenSSL --with-ssldir=DIR SSL base directory for certificates (/etc/ssl) SSL options. --with-pop3d Build POP3 server (default) Build pop3d binary. It still has to be separately enabled from configuration file. --with-passwd Build with /etc/passwd support (default) --with-passwd-file Build with passwd-like file support (default) --with-shadow Build with shadow password support (default) --with-pam Build with PAM support (default) --with-ldap Build with LDAP support --with-vpopmail Build with vpopmail support (default) --with-static-userdb Build with static userdb support (default) --with-pgsql Build with PostgreSQL support Specify which authentication modules to use. Disabling them give you a few bytes smaller binary, but not much else. Dynamic Authentication Modules ------------------------------ Dovecot can also dynamically load authentication modules from $prefix/lib/dovecot/auth/ directory. Binary packages builders should use them for auth modules which require external libraries (eg. LDAP and vpopmail). There's no standard way to build them as modules currently, but something like this should work: gcc -shared -fPIC -DHAVE_CONFIG_H -DUSERDB_LDAP -DPASSDB_LDAP \ -I../.. -I../lib -I../lib-settings \ db-ldap.c userdb-ldap.c passdb-ldap.c -o ldap.so \ ../lib-settings/libsettings.a -lldap gcc -shared -fPIC -DHAVE_CONFIG_H -DUSERDB_PGSQL -DPASSDB_PGSQL \ -I../.. -I../lib -I../lib-settings -I/usr/include/postgresql \ db-pgsql.c userdb-pgsql.c passdb-pgsql.c -o pgsql.so \ ../lib-settings/libsettings.a -L/usr/lib/postgresql -lpq gcc -shared -fPIC -DHAVE_CONFIG_H -DUSERDB_VPOPMAIL -DPASSDB_VPOPMAIL \ -I../.. -I../lib userdb-vpopmail.c passdb-vpopmail.c -o vpopmail.so \ -lvpopmail Including libsettings.a in ldap.so and pgsql.so is kind of annoying, but it's not needed elsewhere in dovecot-auth. Dynamic IMAP and POP3 Modules ----------------------------- If imap_use_modules or pop3_use_modules is set to yes, Dovecot will load all *.so modules from directory pointed by imap_modules or pop3_modules. These modules can do anything, they're only expected to contain <module name>_init and <module name>_deinit functions which are called.
