    I'd like to thank everyone who replied with useful suggestions to
    my mail server request. It would be too much to post all the
    replies, so....

    The consensus seems to be that a solution using separate machines
    for virus and spam scanning ahead of the server that provides
    smtp and pop services to the users would be a more 'elegant'
    solution than bigger iron.

    The solution that seems good to me after sifting all the
    responses is to load-balance port 25 and feed 2 or 3 machines
    that virus and spam scan email and then relay it to the MTA on
    the machine with the user's mailboxes.

    I'm using 'balance' from ports to load balance our Citrix servers
    and it seems to work quite well. I will probably try this for
    port 25.

    Christian Damm asked questions regarding the ratio of spam to
    ham, and number of virus emails. I was suprised to see that we
    are scanning and rejecting at least 2000 emails a day for spam
    and about 30 for viruses. IOW, there are more spams than
    legitimate emails. 'sma' says we are doing about 2700 emails
    per day.

    So thanks, Christian, Ari, Chuck, Matthew, Freddie, Lawrence and
    Steve. All good suggestions.

    Now...how do I do this in between fixing XP problems?

    -Jim
