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 imap-master.

SSL/TLS
-------

GNUTLS v0.5.5 or later is required to enable SSL and TLS support. OpenSSL
isn't supported. 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-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-vpopmail         Build with vpopmail support (default)

Specify which authentication modules to use. Disabling them give you a few
bytes smaller binary, but not much else.

  --with-gnutls           Build with GNUTLS (default)

Use GNUTLS for SSL and TLS support.
