We need to handle about 500,000 emails per day. We have about 30,000 users, so we need a lot of storage. Our current plan was to implement the following. 2 SMTP only servers. 3 NFS servers with RAID and SCSI 2 POP3 servers. But that leads us to questions such as - - what would be the best way to authenticate? - would the NFS servers need gig nic's? or dual bonded 100Mbit cards? - what smtp server and what pop3 server to use (we want to use Maildir) - what raid level? Any suggestions on how to implement an email system to handle the load stated above would be greatly appreciated. Thanks David
