INSTALL Instructions for fetchmail
+If you have installed binaries (e.g. from an RPM) you can skip to step 5.
+
+If you are a Linux system packager, be aware that the build process generates
+an RPM spec file at fetchmail.spec, and you can "make rpm" to generate an
+RPM and SRPM.
+
+The Frequently Asked Questions list, included as the file FAQ in this
+distributions, answers the most common questions about configuring and
+running fetchmail.
+
+1. USEFUL THINGS TO INSTALL FIRST
+
+If you want support for RFC1938-compliant one-time passwords, you'll
+need to install Craig Metz's OPIE libraries first and *make sure
+they're on the normal library path* where configure will find them. Then
+configure with --enable-OPIE, and fetchmail build process will detect
+them and compile appropriately.
+
+Note: there is no point in doing this unless your server is
+OTP-enabled. To test this, telnet to the server port and give it
+a valid USER id. If the OK response includes the string "otp-",
+you should install OPIE. You need version 2.32 or better.
+
+The OPIE library sources are available at ftp://ftp.inner.net/pub/opie.
+You can also find OPIE and IPV6-capable servers there.
+
+Building in IPv6 support or the IPsec patches REQUIRES that Craig
+Metz's inet6-apps kit be installed; the IPsec patches require that the
+kit be built with network security API support enabled. The kit can be
+gotten from ftp.ipv6.inner.net:/pub/ipv6 (via IPv6) or ftp.inner.net
+/pub/ipv6 (via IPv4).
+
+2. CONFIGURE
+
Installing fetchmail is easy. From within this directory, type:
./configure
(e.g. you have gcc but want to compile with cc), set the environment
variable CC before you run configure.
+The configure script accepts certain standard configuration options.
+These include --prefix, --exec-prefix, --bindir, --infodir, --mandir,
+and --srcdir. Do `configure --help' for more.
+
+POP2 support is no longer compiled in by default, as POP2 is way obsolete
+and there don't seem to be any live servers for it anymore. You can
+configure it back in if you want with `configure --enable-POP2', but
+leaving it out cuts the executable's size slightly.
+
+Support for CompuServe's RPA authentication method (rather similar to
+APOP) is available but also not included in the standard build. You
+can compile it in with `configure --enable-RPA'.
+
+Support for authentication using RFC1731 GSSAPI is available
+but also not included by default. You can compile it in with
+`configure --with-gssapi', which looks for GSSAPI support in standard
+locations (/usr, /usr/local). If you set --with-GSSAPI=DIR
+you can direct the build to look for GSSAPI support under DIR.
+
+If you want to build for debugging,
+
+ CFLAGS=-g LDFLAGS=" " ./configure
+
+will do that.
+
+To enable multilingual support using GNU gettext,
+
+ configure --enable-nls
+
+Advanced configuration:
+
+Specifying --with-kerberos=DIR or --with-kerberos5=DIR will tell the
+fetchmail build process to look in DIR for Kerberos support.
+Configure normally looks in /usr/kerberos and /usr/athena; if you
+specify this option with an argument it will look in DIR first.
+
+Unfortunately, there doesn't seem to be good standardization of where
+Kerberos lives. If your configuration doesn't match one of the four
+that fetchmail's configure.in knows about, you may find you have to
+hand-hack the Makefile a bit.
+
+You may also want to hand-hack the Makefile if you're writing a custom
+or bleeding-edge resolver library. In that case you will probably
+want to add -lresolv or whatever to the definition of LOADLIBS.
+
+It is also possible to explicitly condition out the support for
+POP3, IMAP, and ETRN (with configure arguments of --disable-POP3,
+--disable-IMAP, and --disable-ETRN respectively). However, none
+of these wins back more that 3 to 4K on an Intel box.
+
If you're running QNX, edit the distributed Makefile directly. The
QNX values for various macros are there but commented out; all you
have to do is uncomment them.
-Next run
+3. MAKE
+
+You may find you need flex at version 2.5.3 or greater to build
+fetchmail. The stock lex distributed with some versions of Linux does
+not work -- it yields a parser which core-dumps on syntax errors. You
+can get flex at the GNU ftp site, ftp://prep.ai.mit.edu/pub/gnu.
+
+Run
make
-This will compile fetchmail for your system. Note that in order to
-build it, you'll need either flex at version 2.5.3 org greater, or lex.
+This should compile fetchmail for your system. If fetchmail fails to build
+properly, see the FAQ section B on build-time problems. Note: parallelized
+make (e.g. make -j 4) fails due to some weirdness in the yacc productions.
+
+4. INSTALL
Lastly, become root and run
make install
This will install fetchmail. By default, fetchmail will be installed
-in /usr/local/bin, with the man page in /usr/local/man/man1. If you
-wish to change these defaults, edit the Makefile AFTER you run
-"configure" but BEFORE you run "make install." You can easily choose
-a prefix other than /usr/local, or you can choose completely different
-directories for each item.
-
-Note: if you intended to use RPOP (which we don't recommend, you
-should set up APOP), you'll have to make fetchmail suid root. This
-is so it can call rresvport and bind to a privileged port, so the
-server's TCP/IP will see that and know it's OK to let it bind to
-a privileged port at the other end.
-
-See the man page or the file sample.rcfile for a description of how to
+in /usr/local/bin, with the man page in /usr/local/man/man1. You can
+use the configure options --bindir and --mandir to change these.
+
+NOTE: If you are using an MTA other than sendmail (such as qmail,
+exim, or smail), see the FAQ (section T) for discussion of any special
+configuration steps that may be necessary.
+
+5. SET UP A RUN CONTROL FILE
+
+See the man page and the file sample.rcfile for a description of how to
configure your individual preferences.
-Note: if you have been using popclient (the ancestor of this program)
-at version 3.0b6 or later, do this
+If you're upgrading from popclient, see question F4 in the FAQ file.
+
+6. TEST
+
+I strongly recommend that your first fetchmail run use the -v and -k
+options, in case there is something not quite right with your server,
+your local delivery configuration or your port 25 listener. Also,
+beware of aliases that direct your local mail back to the server host!
+
+This software is known to work with the qpop/popper series of freeware
+POP3 servers; also with the IMAP2bis and IMAP4 servers that are
+distributed with Pine from the University of Washington; also with the
+Cyrus IMAP server from CMU. This covers all the servers normally
+hosted on Linux and *BSD systems. It also works with Microsoft Exchange,
+despite the fact that Microsoft Exchange is extremely broken (returns
+incorrect message lengths in LIST responses).
+
+7. REPORTING BUGS
-(cd ~; mv ~/.poprc ~/.fetchmailrc)
+You should read the FAQ file question G3 before reporting a bug.
-in order to migrate.
+8. USE IT
-Enjoy!
+Once you've verified your configuration, you can start fetchmail to
+run in background and forget about it. Enjoy!
