    Hi! This is the ezmlm program. I'm managing the
    webappsecsecurityfocus.com mailing list.

    I'm working for my owner, who can be reached
    at webappsec-ownersecurityfocus.com.

    Messages to you from the webappsec mailing list seem to
    have been bouncing. I've attached a copy of the first bounce
    message I received.

    If this message bounces too, I will send you a probe. If the probe bounces,
    I will remove your address from the webappsec mailing list,
    without further notice.

    I've kept a list of which messages from the webappsec mailing list have
    bounced from your address.

    Copies of these messages may be in the archive.

    To retrieve a set of messages 123-145 (a maximum of 100 per request),
    send an empty message to:
       <webappsec-get.123_145securityfocus.com>

    To receive a subject and author list for the last 100 or so messages,
    send an empty message to:
       <webappsec-indexsecurityfocus.com>

    Here are the message numbers:

       834

    --- Enclosed is a copy of the bounce message I received.

    By the way, any of you have more suggestions on my original question - how
    to display HTML with the active stuff removed?

    I'm trying to display HTML as _HTML_, not text. Displaying HTML as text is
    near trivial.

    Thanks,
    Link.
