    We are in the process of evaluating our current student email solution here
    at the University and I have been asked to develop some estimates of the
    time it takes to research, test and implement this.

    The new system must support 35,000 users with about 1500 concurrent
    connections. More than likely the setup will have redundant web front ends
    (2 servers running SquirrelMail, IMP, etc), 1 mupdate server, 2 frontend
    machines and 2 backend Cyrus mail stores. It will run on top of Linux
    (RHEL 4 probably).

    We are familiar with UW IMAP server so we have to learn the differences to
    go to Cyrus, especially the aggregator, backup/recovery, cyradm, etc. So
    keep that in mind.

    If anyone has any data that would even remotely be helpful I would greatly
    appreciate it. We are comparing Exchange, MiraPoint and this (which is
    much cheaper) but people now want to compare accurate estimates of people
    resources to implement it. To me, that is like asking me how long it would
    take me to learn [place any abstract task here that you have never done].

    Regards,
