hello
Thanks for your answer , MY problem will be IMAPS connections I dunno how much I will have but it would be possible that we'll have 4000/6000 imaps concurent connections during working hours .
POP3 users will be very few

Frank,
Here we have approx. 200K users with 4000 concurrent connections(90% POP3 users) All servers in virtual environment Vmware, supermicro servers and Netapp Metrocluster storage solutions (nfs storage with 10G ethernet network) POP3 sessions take betwen 40 and 300 milisecons at connect, auth and list. All accounts lives in LDAP, CentOS 5 and exim like a mta relay.
Regards
