<disclosure> I am a reseller for a line of products by SonicWALL.com</disclosure> I'm getting inundated by SPAM too and it's probably more then doubled in the past 4 months or so. I trying to work this out too. I would say also recommend making SPF entries for all of the domains you manage. RDNS, MX and A records checks don't really do the job to reduce SPAM if you are an ISP/ASP like me -- cause a lot of eMail Servers out there are really configured correctly and cutomers complain they don't get eMail. You can check to see how well you eMail servers are set up by going to DNSReport.com and type in your domain and click on the "DNS Report" button. I would like to see a C version of the SPF filter which could go a long way to knock out a lot of SPAM -- the current PL version of the filter is a litte slow. Check out www.OpenSPF.org. Depending on the volume of eMail you get -- separate external filters could do the job. I think the line of Security products by SonicWALL can help you. I am using this following tiered approach. My SonicWALL Firewall PRO 2040 (or soon to be upgraded PRO 4060) does the Anti-virus and Anti-SpyWare filtering at the Firewall along with RBL Spamhaus.org plus Intrusion Protection. This way the Firewall severers the TCP connection before the MTA will even see it. For example I just turned on RBL Spamhaus.org on the Firewall this past Sunday and over 60,000 connections have been blocked since then. By doing this at the Firewall I also lighten the load on the xMail Server. The next layer I plan to install soon is the SonicWALL eMail Security Server which comes in appliance or Windows Software Only versions which filters out the SPAM. The advantage of this product that they gather signatures from about 1M Desktops to help determine what is SPAM or not in real time. Again this is a separate standalone pre-filter to the xMail Server. The eMail Security Server also has subscriptions for McAfee and Kaspersky if you don't want to do or the need the SonicWALL Firewall thing. This is only one idea -- if you look at www.xMailServer.org you can find various Plugins for spam filtering solutions and other things. However, keep in mind these scripts run out of process from xMail and can slow down the server xMail lives on -- so make sure you test everthing and monitor the server after you add something. I hope this helps... Good Luck...
