   but please do not give it away altered or as part of another system.
   The essence of "user-supported" software is to provide personal
   computer users with quality software without high prices, and yet to
   provide incentive for programmers to continue to develop new products.

 - If you find this program useful and find that you are using and
   continue the use of the MTA-package after a 30 days trial period,
   you must register the MTA-package as described below;

 - Non-commercial can get a license for the usage up to this release
   of the MTA-package for a small amount of money. Look into the
   details in REGISTER.MTA. Previous registered users will receive
   a big reduction to upgrade to the newer versions. These users
   should look into the details in UPGRADE.MTA.
   For Non-commercial users there is a POSSIBILITY to submit to one
   of the special contracts as explained in the file REGISTER.MTA.

 - Commercial usage of MTA will cost somewhat more. Also, a so called
   'closed' Bulletin Board System (a system where the user must pay
   direct to the SysOp to get full access) is has to pay more than
   a Non-commercial user. Both types of users should look into the
   details in REGISTER.MTA;

 - The registration of the MTA-package will license ONE copy for use on
   any computer at any one time, as long as the usage confirms to the
   type of registration you have done (so NON-commercial usage when you
   have a non-commercial license);

 - Anyone distributing the MTA-package for any kind of remuneration must
   first contact the Author at the address above for authorization.

 - You are encouraged to pass a copy of the MTA-package along to your
   friends for evaluation.  Please encourage them to register their
   copy if they find that they can use it;

 - When you are a non-commercial user of MTA and you are depending
   on the software, you can consider to pay a small amount of
   money for service. The terms for this option can be found in
   the file REGISTER.MTA.

 - Support on MTA, when used in a non-commercial environment, is
   available even when you don't enter a service contract, but the
   payed users (both commercial users and non-commercial users with
   a service contract) have higher priority;

 - Problems and suggestions can be entered in the FidoNet <tm> Echomail
   conference <tm> called DISP (international). Entering this echo does
   not exclude you of the duty to register the MTA-package, though users
   who evaluate the product can enter the echo for questions;

 Newer versions and contacting the author
 ────────────────────────────────────────
 The newest version of MTA is always available on 2:512/100 (Remote
 Access Support). You can obtain MTA in three ways:

 - Logging on to 2:512/100.
   In this case you have the possibility to look at tons of inter-
   resting files with specialized area's for RA and so on. It is a
   so called 'closed' board. Peeking around will cost nothing, you
   must pay for full access. 2:512/100 is the real start of all
   DISP programs in the real world. DISP-HQ (2:512/100.5) is a board
   you cannot access, but my BOSS will always get the newest version
   first;

 - Logging on to your own BBS;
   Chances are, that you will find an older version (international
   users) because it will take some time for the new version to
   'bleed' thru the net;

 - Update service;
   You can enter a special update service (read REGISTER.MTA).


 If you think you have found problems in MTA, or in any other case,
 you wish to contact the author, you can send me:

 - A letter to the address you can find in the header of this file;
 - A NetMail <tm> message to Rob Van.hoeven (please mind the point
   between Van and Hoeven) at 2:512/100;
 - A Message in the FidoNet <tm> DISP echomail <tm> area;


 Description
 ──────────────────────────────
 This utility program is designed for a BBS-configuration, working
 with MTA, normal users won't have much fun with this program !!!

 When you want to include a file with CRC's of the current files
 inside the compressed file as a normal file in the compressed
 file (for viral check or something else), you can use normal
 CRC-routines like CRC.EXE or CRC32.EXE. In this case, look into
 the file MTABETWN.BAT (inside MTA__BAT.EXE).

 There are two problems with this kind of calls:

 - The number of files CRC'ed depend on the CRC-routine itself
   (can in use *.*, can output be redirected, can lower directories
   also be included in the CRC mechanism);
 - The way you work is somewhat 'non-standard';

 I can imagine you would like ALL files to be CRC'ed. Currently there
 is a good alternative for a somewhat 'standard' type of CRC and that
 is McAfee's VALIDATE.COM <tm>. This program has only one limitation,
 you can only validate one file at a time.

 MTA_CRC will create a file with output of all VALIDATE calls for all
 files in the current and lower (if the output of the compressed
 source was recursive and the target compressor supports this).

 MTA_CRC must be called somewhere like this:

 MTA_DIR filename

 'Filename' must point to a full (path, name) filename in ANOTHER
 directory than the current  (because otherwise 'filename' is also
 listed in the directory) and MTA_CRC's output will be redirected
 this file. DO NOT use the redirection characters. MTA_CRC will
 deal with them internally (>>filename).

 If you DO NOT use the parameter in the call, MTA_CRC will create
 a file VALIDATE.CRC in the current directory, containing all
 files in that (and lower) directory.

 Please look into MTABETWE.BAT (inside MTA__BAT.EXE) for an example
 of MTA_CRC's usage.
