define Package/postfix/description
 Postfix is Wietse Venema's mailer that started life as an alternative to the widely-used Sendmail program. Postfix attempts to be fast, easy to administer, and secure, while at the same time being sendmail compatible enough to not upset existing users. Thus, the outside has a sendmail-ish flavor, but the inside is completely different.

#
# 1. Compile the package with current file
# 2. Execute the following command on target device:
# 	postconf -d > /tmp/main.cf.new
# 3. Transfer /tmp/main.cf.new file to the build system
# 4. Execute the following command:
# 	cat /tmp/main.cf.new | ( echo '# DO NOT EDIT THIS FILE. EDIT THE MAIN.CF FILE INSTEAD. THE'; echo '# TEXT HERE JUST SHOWS DEFAULT SETTINGS BUILT INTO POSTFIX.'; echo '#'; grep -v ^alias_maps\ = |grep -v ^alias_database\ = |grep -v ^command_directory\ = |grep -v ^config_directory\ = |grep -v ^daemon_directory\ = |grep -v ^data_directory\ = |grep -v ^default_database_type\ = |grep -v ^html_directory\ = |grep -v ^mail_spool_directory\ = |grep -v ^mailq_path\ = |grep -v ^manpage_directory\ = |grep -v ^meta_directory\ = |grep -v ^mydomain\ = |grep -v ^myhostname\ = |grep -v ^mynetworks\ = |grep -v ^mynetworks_style\ = |grep -v ^newaliases_path\ = |grep -v ^queue_directory\ = |grep -v ^readme_directory\ = |grep -v ^sample_directory\ = |grep -v ^sendmail_path\ = |grep -v ^shlib_directory\ = |grep -v ^smtputf8_enable\ = ) > files/main.cf.default
