Clients sending mail slowly
Suse server used as web server and mail server.
The client machines were sending mail very slowly until somebody mentioned to me the /etc/hosts file, by putting the client IP address in the file, all seems OK.
This was OK until suddenly ALL the computers on the network need to send mail, and not wanting to add in every IP address seperately....
I know there must be way to add in the whole network.. but where do I start?
Ta in advance
