Hi Antonio! How can i test if the RAM is enough and the hard-disk are OK for Imap Server? I can tell you the CPU is working about 0,3 / 0,6 %. Thank you, cheers! Francesco

You said "I think it is ok", so you better test it... And check hard disks also... About anything with the config I can't help you. I think you would have to provide more info on how you installed it. António Lima ________________________________ De: Service, ColliniConsulting S.a.s.

The mailServer is in a DMZ zone. When lots of people are connected, imap client slowdown, and i can see this problem by typing: telnet localhost 143... it waits for about 60/90 seconds before appearing the Imap Service banner. I have also raised up the max per Ip and max daemons, and i have the -nodnslookup in order to avoid reverse DNS resolution slowdown. I think RAM is OK, the Server does not use swap and i do not know how to solve it... Are there some other parameters/workaround to avoid this slowdown problems? Thank you, cheers! Francesco, from Italy
