I know of no alternatives, hence I'm rolling my own. > Just thought I should make a couple comments, it's not a message to change or correct Mel's message but rather just a idea on a possible solution I have deployed and would like input and experience/results relayed to me. Put whatever MTA you want, I use postfix primarily. sendmail would work too, but I don't know exim or qmail. Install OpenBSD's spamd (that works with PF, and ipfw support is early, but there) on the host to block the (at last count) ~460k hosts and subnets that are known spammers so your MTA doesn't even have to mess with it. Include DNS Blacklisting support with your MTA. These are the servers that have mistakenly sent out a spam and gotten caught. DNSBL will report to the client that it's being blocked and how to remove it. I'd love to hear success stories with this. Both pieces together work very well, and I am still working on seeing if any spam does come through. If spam does come through, a product like dspam or spamassassin could finish off the job. I don't have a live domain, so I can give directions if anybody's interested. Maybe one day I'll write up an article for this. I ask please - for those who are interested in trying this, to give me the success or not-so-success stories so I can fine tune it and work out the missing link. --Tim
