For starters, take a look at maillog (/var/log/maillog on my system) to check whether any SA child processes are timing out. If they are, you need to find out why processing those messages took so long and, if possible, speed that up, e.g. if RBL checks or domain name lookups are slow, consider running a local caching DNS. If that doesn't turn up anything obvious, use performance monitoring tools (sar, iostat, mpstat, etc) to see what is consuming the system resources: you have to know where and what the bottleneck(s) are before you can do anything about them. You can find these tools here: http://freshmeat.net/projects/sysstat/ if they aren't part of your distro's package repository. Martin
