what about creating a new section "Mail applications"?

Here I use a different approach using sed inside exim.mk:

( sed -e 's,^BIN_DIR.*$$,BIN_DIRECTORY=/usr/bin,' \
      -e 's,^CONF.*$$,CONFIGURE_FILE=/etc/exim.conf,' \
      -e 's,^# INCLUDE.*$$,INCLUDE=-I$(TARGET_DIR)/usr/include,' \
      -e 's,^PCRE_CONFIG.*$$,# PCRE_CONFIG=no,' \
      -e 's,^# PCRE_LIBS.*$$,PCRE_LIBS=-lpcre,' \
      -e 's,^# HAVE_ICONV.*$$,HAVE_ICONV=yes,' \
      -e 's,^# AUTH_CRAM_MD5=.*$$,AUTH_CRAM_MD5=yes,' \
      -e 's,^# AUTH_DOVECOT=.*$$,AUTH_DOVECOT=yes,' \
      -e 's,^# AUTH_PLAINTEXT=.*$$,AUTH_PLAINTEXT=yes,' \
      -e 's,^# LOOKUP_PASSWD=.*$$,LOOKUP_PASSWD=yes,' \
      -e 's,^# WITH_CONTENT_SCAN=.*$$,WITH_CONTENT_SCAN=yes,' \
      -e 's,^# SUPPORT_TLS=.*$$,SUPPORT_TLS=yes,' \
      -e 's,^# TLS_LIBS=.*$$,TLS_LIBS=-lssl -lcrypto,' \
      -e 's,^# PID_FILE_PATH=.*$$,PID_FILE_PATH=/var/run/exim.pid,' \

        ); \

This should imho be extended to options in Config.in for different mail 
environments, similar to the Debian packages exim4-daemon-heavy & exim4-
daemon-light.

I have to add that buildroot does not create a rootfs here, it delivers 
binaries for my personal mailserver package which is used in another distro 
with its own init system, therefore I can not review your init script.
