[Dovecot] scalability

[Jonathan Tripathy]

Hi Folks,

How scalable is dovecot. Do you think a machine with a dual core 2.8Ghz 
processor and 2GB of RAM would do a business with 600 users? This server 
will have a 100Mbps link to the net, however it will be access by the 
business using a couple of ADSL lines (Roughly 7Mbps each).

This machine will also be running Postfix

Your help is appreciated

Cheers

Jonny
