# After this you need to configure your mailman:
# (Take a look to: /usr/share/doc/mailman-2.1.9/INSTALL.REDHAT)
#
# 1. Create your site password:
#
#	/usr/lib/mailman/bin/mmsitepass
#
# 2. Define the first mailing list. 
#
#	/usr/lib/mailman/bin/newsite mailman@domain.tld
#
# 3. Restart the Apache web server
#
#	/sbin/service httpd restart
#
# 4. Start mailman daemon
#
# 	/sbin/service mailman start
#
#
# ... and thats all folks! :)
