Another topic led me to look at my mail.log and I notice the following entries constantly:
Apr 29 19:32:19 config: Warning: service auth { client_limit=1000 } is lower than required under max. load (2500)
Apr 29 19:32:19 config: Warning: service anvil { client_limit=1000 } is lower than required under max. load (2003)
Anyone able to shed some light on what they are and if it is something I need to address?
