Hi John* >> I have to ask, is your mail really so time-critical that you're not willing to wait two minutes for spamd do to its job? * No reason really, initially it was set to the default (300secs) which I thought was what was causing the errors in the logs. I've set it to 60secs just as a test to eliminate all possibilities. So far all seems be fine on the server. I am going to wind this up over the next few days to see how it pans out.
Many thanks
