I wanted to throw a question out and see if anyone has any ideas whether this will work. We are planning to expand to handle an insane amount of requests. The system that we are designing is as follows: 1 External Storage array (1+ TB) 4 Clustered Imail 5.x servers (all tie into the storage via 1 logical drive letter) 4 Clustered Web interface servers (these will handle all calls between the user and the mail servers) The external storage array will contain ALL Imail user accounts and thier mail. All user information will be stored in an external SQL server. The idea is that the 4 clustered servers will "share" all Imail accounts and pass requests to each other based on fail overs and load balancing. The question is, can Imail handle this? Each email retrieval (POP, IMAP) call will be made through a single server in the cluster, but SMTP managment can be handled by ALL servers in the cluster. Will Imail's file lock control what mail in the spool is already being handled by another server? I know that Imail modifies the extension of a file in the spool if it is being used, but what if Mail Server 1 and Mail Server 2 BOTH try to access the same file at the same time? Will this be handled in the same manner as 2 different SMTP processes doing the same? Any advice would be appreciated.
