Trapping banner displayed by sshd during ssh / scp?

        Hi everyone,

        I'm hoping someone can help me with this annoyance that I'm having with
    ssh & scp. I've written a small program which does the following:
        1) uses ssh (with rsa authentication, no password needed) to execute
    two commands on a remote system.
        2) scp's a dozen-or-so files to a remote system
        3) uses ssh (rsa authentication again) to execute another two commands
    on the remote system.

        I'm running it through cron, and I'm having difficulty figuring out how
    to trap the login banner displayed by the remote system's sshd. The other
    output of my program is being sent to me via email, and I'd like to discard
    the banner (because it appears a bunch of times, and it's useless,
    repetitive information for the purposes of my program). Essentially, I get
    two emails:
        One from the cron daemon on my local system containing the un-trapped
    output from my program:

        ****************************************
        * Remote System Banner *
        ****************************************
        repeated numerous times

        The other email contains actual information I want.

        Now, I know that you can configure the sshd on the remote system to turn
    off display of that banner, but I've been told by my system admins that this
    is against corporate policy, since it contains a legal notice indicating,
    essentially, "if you aren't authorized to be here, you're toast." Is there
    some _other_ way of trapping this output? Or do I need to set up a mail
    filter and redirect these emails to /dev/null?

        Operating environment is open ssh (server + client), on Solaris 8 (both
    systems), and the program I'm using to do this is a very simple korn shell
    script;

        Any thoughts or help would be greatly appreciated.

        Thanks,

        Kevin Pease
