good

to block spam ... ( bounce it before you have to deal with it in any form )
	
	- use a closed mailing list, ( members only )
	( that you've already done )

	- spammers will probably not be members and probably will not 
	subscribe .. spam it .. and unsubscribe

- additional spam prevention rules ... may or may not work for you
  ( aka some consider it bad practice .. others use it .. just depends
  ( on ones tolerance for spam and what you're willing to do to stop it 

	- spam is best stopped at the MTA ... not after you got the spam

	- deny html-based emails ( no reason to have html-based emails )
	( that gets rid of 95% of the junk )

	- deny all sending MTA access if it does not have a reverse dns
	entry

	- deny incoming emails to fake email addy on your end ..

	- it's lot harder to decide to if the sendimg emails are fake

	- rejecting emails from other domains will be a problem when
	deny incoming emails from [email protected] that was sent from
	isp-hosting-domain.com that hosts joe's site
		( ie. sending domain must match reply domains )
		
	- endless list of stopping spam rules

- my personal issue with spam assassin... and equivalents
	- it does not deny incoming connections from (suspect) spammers
	- i still have to deal with the spam after it was received
	( the above 2 requirements being important requirements for me )

	- it flags legit emails as spam when its not
	- i have to create mroe special folders for suspect spam
	- i have to teach it ( setting arbitrary "spam numbers" )
