-1. CONFIGURE
+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 http://www.inner.net/pub/opie/
+You can also find OPIE and IPV6-capable servers there.
+
+Building in IPv6 support *requires* glibc 2.1.1 (or newer) or
+that Craig Metz's inet6-apps kit be installed.
+The IPsec patches *requires* inet6-apps kit.;
+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:
The configure script accepts certain standard configuration options.
These include --prefix, --exec-prefix, --bindir, --infodir, --mandir,
-and --srcdir. Do `config --help' for more.
+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 Microsoft's NTLM authentication method is also available
+but also not included in the standard build. You can compile it in
+with `configure --enable-NTLM'.
+
+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.
+
+Hooks for the OpenSSL library (see http://www.openssl.org/) are
+included in the distribution. To enable these, configure with
+--with-ssl; they are not included in the standard build.
+
+If you want to build for debugging,
+
+ CFLAGS=-g LDFLAGS=" " ./configure
+
+will do that.
+
+To specify a fallback MUA in case local port 25 doesn't respond, do one of:
+
+ configure --enable-fallback=procmail
+ configure --enable-fallback=sendmail
+
+A disadvantage of using procmail is that local alias expansion
+according to /etc/aliases won't get done if we fall back to it.
+
+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.

Run
make

-If linking fails to resolve atexit(), go find a compiler that isn't lying
-about being ANSI-compliant (such as gcc). Some SunOS users have had this
-problem.

-3. INSTALL
+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 are using exim, you must configure it to accept local
-addresses as valid RCPT TO lines.
-
-4. SET UP A RUN CONTROL FILE
+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.
-See the man page or the file sample.rcfile for a description of how to
-configure your individual preferences.
+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.
-Note: if you have been using popclient (the ancestor of this program)
-at version 3.0b6 or later, do this
+5. SET UP A RUN CONTROL FILE
-(cd ~; mv ~/.poprc ~/.fetchmailrc)
+See the man page for a description of how to configure your individual
+preferences.
-in order to migrate. Be aware that some of popclient's unnecessary
-options have been removed (see the NOTES file for explanation). You
-can't deliver to a local mail file anymore or to standard output any
-more, and using an MDA for delivery is discouraged. If you throw
-those options away, fetchmail will now forward your mail into your
-system's normal Internet-mail delivery path.
+If you're upgrading from popclient, see question F4 in the FAQ file.
-Actually, using an MDA is now almost always the wrong thing; the MDA
-facility has been retained only for people who can't or won't run a
-sendmail-like SMTP listener on port 25. The default, SMTP forwarding
-to port 25, is better for at least two major reasons. One: it feeds
-retrieved POP and IMAP mail into your system's normal delivery path
-along with local mail and normal Internet mail. Two: because the port
-25 listener returns a positive acknowledge, fetchmail can be sure
-you're not going to lose mail to a disk-full or some other
-resource-exhaustion problem.
+6. TEST
-If you used to use -mda "procmail -d <you>" or something similar, forward
-to port 25 and do "| procmail -d <you>" in your ~/.forward file.

-A couple of users have reported that some recent (post-2.7.2) versions
-of gcc seem to have an optimizer bug that affects fetchmail. If your
-fetchmail core dumps (especially near startup) try recompiling without
--O. Alternatively, you can drop back to gcc 2.7.2 or below.
