I have a server with similar load but do not have problems at all what calls attention is that you use ide disk on a server ... and your swap is in use what means your ram memory is too low btw without sysctl hw and kernel compile options and eventually sysctl options it's hard to give you hints general hint: why notifying the virus sender and spammer? you believe they care or even exist? you are creating part of your own troubles since most of this notify msgs are coming back to you as delivery error:) JM Mike Tancsa (mike@sentex.net) escreve: > > > We have separate inbound and outbound smtp servers and I am looking to > better tune the boxes (2 of them) that spool my network's outbound > mail.
