If you have a Netapp then you have to deal with Linux NFS issues which aren't fun. If you have a cluster of storage machines and front-end SMTP servers to direct delivery to the correct back-end machine as well as Perdition to proxy POP and IMAP to the correct back-end machine then you can scale easily without dealing with NFS. > This setup is proven to be very scalable, when you want to add another > 20k users, just add some servers :) You have to either be doing something very intensive or very wrong to need more than one server for 20K users. Last time I did this I got 250K users per server, and I believe that I could have easily doubled that if I was allowed to choose the hardware. I used Qmail (not my choice), Courier, Perdition, IMP, MySQL (for IMP), and was moving it to OpenLDAP at the time I left that project. -- http://www.coker.com.au/selinux/ My NSA Security Enhanced Linux packages http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/~russell/ My home page -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
