[SDBUG] OpenBSD's "spamd" usable on FreeBSD?

Fri Feb 9 08:06:24 PST 2007

For a SPAM filtering Mail system/server I have found Mike Simerson's  
Mail-Toaster (http://www.mail-toaster.com) works pretty well and  
pleases the geek in me but is manageable vi a web interface for the  
non-technical. My Step Father loves it.  ;-)

P.S. Mike, Long time no read and I am in Texas now.  ;-)
