Am I being thick, or did you miss a point or two? What business uses mailing-lists? Iff they did, you add that-mail-list to the DB by hand (umm 3 seconds with php) The business gets some 500 spam / day. spamassassin gets about 300-400 (The spammers are getting really clever). As an EG dontronics won't even release their email address. You as a paying customer have to go through hoops to get it. They seem to be doing OK. A reply saying "to help us with spam, please send one mail" seems quite reasonable to us engineering types http://www.dontronics-shop.com Dontronics PO Box 595 Tullamarine Victoria 3043 James -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
