I have plenty of colleagues who run their own mail servers from residential connections and they know how to set-up their machines. Understandably, they are miffed by having to pay for a business line, or rack space in a data centre, when they are perfectly capable for doing this with a spare box at home. Therefore they set-up their own server.
I don't fancy blocking these people or the enthusiasts who are quite capable of running their own server. Back to the Stan's pcre file:- I've been running through the logs for rejects specifically caused by this file (or prepends). However I did not see any. Is there a string I could search for, and how could I white list IPs instead of editing the pcre file? Regards.
