+###############################################################################
+# Exim is built by default to support the SMTP STARTTLS command, which implements
+# Transport Layer Security using SSL (Secure Sockets Layer). This requires you
+# must install the OpenSSL library package or the GnuTLS library. Exim contains
+# no cryptographic code of its own.
+
+# If you are running Exim as a (TLS) server, just building it with TLS support
+# is all you need to do, as tls_advertise_hosts is set to '*' by
+# default. But you are advised to create a suiteable certificate, and tell
+# Exim about it by means of the tls_certificate and tls_privatekey run
+# time options, otherwise Exim will create a self signed certificate on
+# the fly. If you are running Exim only as a (TLS) client, building it with
+# TLS support is all you need to do.
+#
+# If you are using pkg-config then you should not need to worry where
+# the libraries and headers are installed, as the pkg-config .pc
+# specification should include all -L/-I information necessary.
+# Enabling the USE_*_PC options should be sufficient. If not using
+# pkg-config, then you have to specify the libraries, and you might
+# need to specify the locations too.
+
+# Uncomment the following lines if you want
+# to build Exim without any TLS support (either OpenSSL or GnuTLS):
+# DISABLE_TLS=yes
+# Unless you do this, you must define one of USE_OPENSSL or USE_GNUTLS
+# below.
+
+# If you are building with TLS, the library configuration must be done:
+
+# Uncomment this if you are using OpenSSL
+# USE_OPENSSL=yes
+# Uncomment one of these settings if you are using OpenSSL; pkg-config vs not
+# and an optional location.

+# Uncomment this if you are using GnuTLS
+# USE_GNUTLS=yes
+# Uncomment one of these settings if you are using GnuTLS; pkg-config vs not
+# and an optional location. If you disable SUPPORT_DANE below, you

+# If using GnuTLS older than 2.10 and using pkg-config then note that Exim's
+# build process will require libgcrypt-config to exist in your $PATH. A
+# version that old is likely to become unsupported by Exim in 2017.
+
+# The security fix we provide with the gnutls_allow_auto_pkcs11 option
+# (4.82 PP/09) introduces a compatibility regression. The symbol is

+# building Exim.

+# If you are running Exim as a server, note that just building it with TLS
+# support is not all you need to do. You also need to set up a suitable
+# certificate, and tell Exim about it by means of the tls_certificate
+# and tls_privatekey run time options. You also need to set tls_advertise_hosts
+# to specify the hosts to which Exim advertises TLS support. On the other hand,
+# if you are running Exim only as a client, building it with TLS support
+# is all you need to do.
+
+# If you are using pkg-config then you should not need to worry where the
+# libraries and headers are installed, as the pkg-config .pc specification
+# should include all -L/-I information necessary. If not using pkg-config

+
+# Additional libraries and include files are required for both OpenSSL and
+# GnuTLS. The TLS_LIBS settings above assume that the libraries are installed
+# with all your other libraries. If they are in a special directory, you may

# it replaces the value with what is defined here. Commenting this setting

# Exim will first look for a configuration file whose name is that defined
# by CONFIGURE_FILE, with the effective uid tacked on the end, separated by
-# a period (for eximple, /usr/exim/configure.0). If this file does not exist,
+# a period (for example, /usr/exim/configure.0). If this file does not exist,
# then the bare configuration file name is tried. In the case when both
# CONFIGURE_FILE_USE_EUID and CONFIGURE_FILE_USE_NODE are set, four files
# are tried: <name>.<euid>.<node>, <name>.<node>, <name>.<euid>, and <name>.

+# Expanding match_* second parameters: BE CAREFUL IF ENABLING THIS!
+# It has proven too easy in practice for administrators to configure security
+# problems into their Exim install, by treating match_domain{}{} and friends
+# as a form of string comparison, where the second string comes from untrusted
+# data. Because these options take lists, which can include lookup;LOOKUPDATA
+# style elements, a foe can then cause Exim to, eg, execute an arbitrary MySQL
+# query, dropping tables.
+# From Exim 4.77 onwards, the second parameter is not expanded; it can still
+# be a list literal, or a macro, or a named list reference. There is also
+# the new expansion condition "inlisti" which does expand the second parameter,
+# but treats it as a list of strings; also, there's "eqi" which is probably
+# what is normally wanted.
