# 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! :)
