The following copyright and license applies to this software:

    IBM PUBLIC LICENSE VERSION 1.0 - SECURE MAILER

    THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS IBM PUBLIC
    LICENSE ("AGREEMENT").  ANY USE, REPRODUCTION OR DISTRIBUTION OF THE
    PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.

    1.  DEFINITIONS

    "Contribution" means:
	a) in the case of International Business Machines Corporation ("IBM"),
	   the Original Program, and
	b) in the case of each Contributor,
	   i)  changes to the Program, and
	   ii) additions to the Program;
	       where such changes and/or additions to the Program originate
	       from and are distributed by that particular Contributor.
	       A Contribution 'originates' from a Contributor if it was added
	       to the Program by such Contributor itself or anyone acting on
	       such Contributor's behalf.
	Contributions do not include additions to the Program which:
	   (i)  are separate modules of software distributed in conjunction
		with the Program under their own license agreement, and
	   (ii) are not derivative works of the Program.

    "Contributor" means IBM and any other entity that distributes the Program.

    "Licensed Patents " mean patent claims licensable by a Contributor which
    are necessarily infringed by the use or sale of its Contribution alone
    or when combined with the Program.

    "Original Program" means the original version of the software accompanying
    this Agreement as released by IBM, including source code, object code
    and documentation, if any.

    "Program" means the Original Program and Contributions.

    "Recipient" means anyone who receives the Program under this Agreement,
    including all Contributors.

    2.  GRANT OF RIGHTS

	a) Subject to the terms of this Agreement, each Contributor hereby
	grants Recipient a non-exclusive, worldwide, royalty-free copyright
	license to reproduce, prepare derivative works of, publicly display,
	publicly perform, distribute and sublicense the Contribution of such
	Contributor, if any, and such derivative works, in source code and
	object code form.

	b) Subject to the terms of this Agreement, each Contributor hereby
	grants Recipient a non-exclusive, worldwide, royalty-free patent
	license under Licensed Patents to make, use, sell, offer to sell,
	import and otherwise transfer the Contribution of such Contributor,
	if any, in source code and object code form.  This patent license
	shall apply to the combination of the Contribution and the Program
	if, at the time the Contribution is added by the Contributor, such
	addition of the Contribution causes such combination to be covered
	by the Licensed Patents.  The patent license shall not apply to any
	other combinations which include the Contribution.  No hardware per
	se is licensed hereunder.

	c) Recipient understands that although each Contributor grants the
	licenses to its Contributions set forth herein, no assurances are
	provided by any Contributor that the Program does not infringe the
	patent or other intellectual property rights of any other entity.
	Each Contributor disclaims any liability to Recipient for claims
	brought by any other entity based on infringement of intellectual
	property rights or otherwise.  As a condition to exercising the rights
	and licenses granted hereunder, each Recipient hereby assumes sole
	responsibility to secure any other intellectual property rights
	needed, if any.  For example, if a third party patent license
	is required to allow Recipient to distribute the Program, it is
	Recipient's responsibility to acquire that license before distributing
	the Program.

	d) Each Contributor represents that to its knowledge it has sufficient
	copyright rights in its Contribution, if any, to grant the copyright
	license set forth in this Agreement.

    3.  REQUIREMENTS

    A Contributor may choose to distribute the Program in object code form
    under its own license agreement, provided that:
	a) it complies with the terms and conditions of this Agreement; and
	b) its license agreement:
	   i)   effectively disclaims on behalf of all Contributors all
		warranties and conditions, express and implied, including
		warranties or conditions of title and non-infringement, and
		implied warranties or conditions of merchantability and fitness
		for a particular purpose;
	   ii)  effectively excludes on behalf of all Contributors all
		liability for damages, including direct, indirect, special,
		incidental and consequential damages, such as lost profits;
	   iii) states that any provisions which differ from this Agreement
		are offered by that Contributor alone and not by any other
		party; and
	   iv)  states that source code for the Program is available from
		such Contributor, and informs licensees how to obtain it in a
		reasonable manner on or through a medium customarily used for
		software exchange.

    When the Program is made available in source code form:
	a) it must be made available under this Agreement; and
	b) a copy of this Agreement must be included with each copy of the
	   Program.

    Each Contributor must include the following in a conspicuous location
    in the Program:

	Copyright (c) 1997,1998,1999, International Business Machines
	Corporation and others. All Rights Reserved.

    In addition, each Contributor must identify itself as the originator of
    its Contribution, if any, in a manner that reasonably allows subsequent
    Recipients to identify the originator of the Contribution.

    4.  COMMERCIAL DISTRIBUTION

    Commercial distributors of software may accept certain responsibilities
    with respect to end users, business partners and the like.  While this
    license is intended to facilitate the commercial use of the Program, the
    Contributor who includes the Program in a commercial product offering
    should do so in a manner which does not create potential liability for
    other Contributors.   Therefore, if a Contributor includes the Program in
    a commercial product offering, such Contributor ("Commercial Contributor")
    hereby agrees to defend and indemnify every other Contributor
    ("Indemnified Contributor") against any losses, damages and costs
    (collectively "Losses") arising from claims, lawsuits and other legal
    actions brought by a third party against the Indemnified Contributor to
    the extent caused by the acts or omissions of such Commercial Contributor
    in connection with its distribution of the Program in a commercial
    product offering.  The obligations in this section do not apply to any
    claims or Losses relating to any actual or alleged intellectual property
    infringement.  In order to qualify, an Indemnified Contributor must:
	a) promptly notify the Commercial Contributor in writing of such claim,
    and
	b) allow the Commercial Contributor to control, and cooperate with
	   the Commercial Contributor in, the defense and any related
	   settlement negotiations.  The Indemnified Contributor may
	   participate in any such claim at its own expense.

    For example, a Contributor might include the Program in a commercial
    product offering, Product X.  That Contributor is then a Commercial
    Contributor.  If that Commercial Contributor then makes performance
    claims, or offers warranties related to Product X, those performance
    claims and warranties are such Commercial Contributor's responsibility
    alone.  Under this section, the Commercial Contributor would have to
    defend claims against the other Contributors related to those performance
    claims and warranties, and if a court requires any other Contributor to
    pay any damages as a result, the Commercial Contributor must pay those
    damages.

    5.  NO WARRANTY

    EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED
    ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER
    EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR
    CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A
    PARTICULAR PURPOSE. Each Recipient is solely responsible for determining
    the appropriateness of using and distributing the Program and assumes
    all risks associated with its exercise of rights under this Agreement,
    including but not limited to the risks and costs of program errors,
    compliance with applicable laws, damage to or loss of data, programs or
    equipment, and unavailability or interruption of operations.

    6.  DISCLAIMER OF LIABILITY

    EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR
    ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT,
    INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING
    WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF
    LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING
    NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION
    OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF
    ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

    7.  GENERAL

    If any provision of this Agreement is invalid or unenforceable under
    applicable law, it shall not affect the validity or enforceability of
    the remainder of the terms of this Agreement, and without further action
    by the parties hereto, such provision shall be reformed to the minimum
    extent necessary to make such provision valid and enforceable.

    If Recipient institutes patent litigation against a Contributor with
    respect to a patent applicable to software (including a cross-claim or
    counterclaim in a lawsuit), then any patent licenses granted by that
    Contributor to such Recipient under this Agreement shall terminate
    as of the date such litigation is filed.  In addition, If Recipient
    institutes patent litigation against any entity (including a cross-claim
    or counterclaim in a lawsuit) alleging that the Program itself (excluding
    combinations of the Program with other software or hardware) infringes
    such Recipient's patent(s), then such Recipient's rights granted under
    Section 2(b) shall terminate as of the date such litigation is filed.

    All Recipient's rights under this Agreement shall terminate if it fails
    to comply with any of the material terms or conditions of this Agreement
    and does not cure such failure in a reasonable period of time after
    becoming aware of such noncompliance.  If all Recipient's rights under
    this Agreement terminate, Recipient agrees to cease use and distribution
    of the Program as soon as reasonably practicable.  However, Recipient's
    obligations under this Agreement and any licenses granted by Recipient
    relating to the Program shall continue and survive.

    IBM may publish new versions (including revisions) of this Agreement
    from time to time.  Each new version of the Agreement will be given a
    distinguishing version number.  The Program (including Contributions)
    may always be distributed subject to the version of the Agreement under
    which it was received. In addition, after a new version of the Agreement
    is published, Contributor may elect to distribute the Program (including
    its Contributions) under the new version. No one other than IBM has the
    right to modify this Agreement.  Except as expressly stated in Sections
    2(a) and 2(b) above, Recipient receives no rights or licenses to the
    intellectual property of any Contributor under this Agreement, whether
    expressly, by implication, estoppel or otherwise.  All rights in the
    Program not expressly granted under this Agreement are reserved.

    This Agreement is governed by the laws of the State of New York and the
    intellectual property laws of the United States of America. No party to
    this Agreement will bring a legal action under this Agreement more than
    one year after the cause of action arose.  Each party waives its rights
    to a jury trial in any resulting litigation.
