Version.....: 5.8c - Feb 25, 2009
Description : Opens up an SMTP connection and sends an email message  
               to multiple recipients.
Input Param : 
     mailhub     char - settable SMTP server name/IP address
                 optionally append :XX where X is a port number of the
                 SMTP server.  25 is default port.
     EmailTo     CHAR - list of email addresses separated by 
                 semicolons or commas (All semicolons will 
                 be replaced by commas so don't include stuff
                 like Smith, John)  <me@myaddress.org>"My Name"
     EmailFrom   CHAR - email address of user originating the email, 
                 the SMTP server should require that this user 
                 is real. Format looks like:
                 <user>@<host>[;<descriptive name>][^replytouser>@<replytohost]
                 Example:
                 foo@bar.com[;Mr. Foo Bar]

                 If you want Delivery or Read Receipts, add a 
                 chr(1) delimiter to the end of the EmailFrom and 
                 then one or two comma delimted logical strings 
                 (Yes or No) for Delivery and Read Receipt
                 respectivley.
                 Example:
                 "foo@bar.com;Mr. Foo Bar" + chr(1) + "yes,no"
                 will give a delivery receipt and no read receipt. 
                 These parameters are strictly optional and not 
                 required.  Delivery and read receipts are always 
                 returned to the EmailFrom address.

     EmailCC     CHAR - list of email addresses separated by 
                 semicolons or commas (All semicolons will 
                 be replaced by commas so don't include stuff
                 like Smith, John) <me@myaddress.org>"My Name"

                 For BCC (blind copies) add a ^B to the end of the address.
                 Example: me@myaddress.org^B

     Attachments CHAR - Comma separated list of attachment descriptions 
                 Format looks like: 
       file[:type=<mimetype>][:charset=<charset>][:filetype=<filetype>]
                 Special Filetypes are:  BINARY, B64ENCODED if you use
                 B64ENCODED make sure to call smtpmail with RemoveEncodedFiles
                 as the EmailTo parameter after sending all your emails
                 or the encoded files will build up in your temporary
                 directory.
     LocalFiles  CHAR - comma separated list of filenames to the files 
                 described in Attachments.  The filenames in this  
                 parameter must either be in the Progress path or
                 have the entire path specified.  In contrast to 
                 filenames in the Attachments are the filenames to 
                 show for the Attachments.
     Subject     CHAR - Subject line
     Body        CHAR - Actual text of the message can be whatever you  
                 want as long as you include the correct Header 
                 information in the MIMEHeader. 
                 If you are just sending plaintext you can leave 
                 the MIMEHeader blank, this is default setting 
                 If you wanted to send HTML you might use: 
                 type=text/html:charset=us-ascii:filetype=ascii
     MIMEHeader  CHAR - [type=<mimetype>][:charset=<chrset>][:filetype=<type>]
     BodyType    char - File/text.  Determines whether a file or text 
                 goes into the message body.

     L_DoAUTH   LOGICAL - yes if authentication is requiered
     C_AuthType CHAR - Type of authentication. Currently supported types:base64 
     C_User     CHAR - The name of the SMTP server user
     C_Password CHAR - The password of the SMTP server user

Output Param: 
     oSuccessful  LOGICAL - Yes the message was succesfully generated
                  No there was some error that prevented message from
                  being successful generated.
                  ? there may have been a problem with a recipient
                  or format of the email.

Notes.......: 
            This program was adapted from a combination of the work of  
            Scott Auge and distributed as part of his mailsdk           
            Scott had laid the groundwork for sending an email with     
            attachments. But his original code did not verify the
            servers response to make sure the data was being sent
            properly.  
            Mario's original work smtpmail.p was a big help in
            developing an understanding of how SMTP works.  His
            program was very elegant in the way it deals with Sockets
            however Scott's work had done much more in the area of 
            including attachments.
            
            SMTP Protocols taken from RFC821
            MIME Protocols taken from RFC1521
            SMTP AUTH taken from RFC2554
            http://cr.yp.to/docs/smtplf.html - CR/LF problem

Disclaimer..: This program is not fully tested especially with  
              regard to the Reading of the Server Responses, and
              encoding   of the MIME message body . 
              
Modifications:
 Sam Schroeder - sschroeder@mn.rr.com                          
 Changed "~n" to CHR(13) + CHR(10) as RFC821 calls for         
 commands to end in <CRLF>, as carriage return and line feed.  
 NOTE: This is not fixed in the MIME section as I was not able
       to test this section.                                   
                                                               
                                                               
                                                               
 6/20/01 Geoff Crawford - for most robustness, it is           
         necessary to loop through the WRITE() on the          
         socket in case if the underlying transport            
         does the write in more than one step.  A              
         simple loop was added.                                
 6/28/01 Steven Lichtenberg - Added checks for server response 
         to ensure the conversation happens.  On initial       
         connection, there may be a significant lag before the 
         server responds. Looping through to recheck for       
         response was necessary                                
 7/3/01  Steven Lichtenberg - Modifications to more fully      
         incorporate Mario's original code andto make the      
         routine more modular.  Added robustness features to   
         ensure the complete/correct delivery of binary        
         attachments through the use of MEMPTR.  Also added    
         the ability to use either                             
         a file or passed text for the message body.  This     
         allows for the options of sending a file as an        
         attachment or as the message body.  Reworked to use   
         event driven principles for cleaner code and easier   
         maintenance.                                          
 7/9/01  Paul Keary - Replaced CHR(13) + CHR(10) with crlf     
         Decreased indentation of some of code to 2 spaces for 
         better readability on character screens.              
         Added code to set Encodedirectory based on OPSYS      
         Capitalized most of the Progress Keywords(anal,I know)
         Found a line with a single period just after the line 
         where cBoundary = "MAIL_BOUNDARY", it appears to have 
         been introduced when the ~n were orginally changed to 
         to CHR(13) + CHR(10).                                 
         Added alternative API that is activated by removing   
         preprocesser PublicVersion                            
         Found logic errors surrounding getsocket code and what
         happens if getsocket doesnot succeed.                 
 7/12/01 Found a problem with the filename used for binary file
         if the input file name is a full path.  On a Unix box 
         it tried to write a file like /tmp//u/htmldocs/...    
         Notice the 2 /'s after tmp.  Modified the code to use 
         a unique filename like en78422  instead of added a #  
         onto the end of the original local file               
         Also found attachbinlist was being delimited with a   
         '<' for binaryfiles instead of a ',' This appeared to 
         a typing error, I am surprised it wasn't noticed b4now
 7/12/01 Mario Paranhos - fixed some tiny bugs in the mime type
 8/30/01 Mark Bremmeyr - Found a problem when body is from a   
         file. Changed GetFile to process attachments and body 
         differently. Body text needed ~n before and after     
         the content of input file.                           
 9/19/01 Paul Keary - Fixed 2 reported problems 
         1. Sending a File as the Body of the message had a bug  
         where a blank line was not inserted before the body of
         the message.                                          
         2. Added a workaround for running in batch-mode based on
         Simon Prinsloo's suggestion of using a DO WHILE loop  
         Also added a secondary mechanism to leave the loop if 
         WriteData has not been called in the last 60 seconds  
         just in case the logical sending is not set to NO by  
         the Read-Handler.                                     
 9/20/01 Steve Southwell - Added the ability to have a descriptive 
         "from".  Reformatted header in FFW format.      
 10/3/01 Steve Southwell - Merged in some changes - did some cleanup
 1/11/02 Steve Southwell - Changed Error with newstate being set to 3 
         instead of 4.   Thanks to "Anonymous" for the fix.
 5/13/02 Paul Keary - Merged in special feature of setting Body to
         File:<FileName> to treat the body as a filename to insert
         in the email shortcut for setting BodyType = "File".
         Added line to reset start-Etime inside WriteData.
 5/13/02 Paul Keary - Added code to support special filetype of 
         B64ENCODED acts just as BINARY filetypes with exception of 
         how the temporary encoded files are treated.
         Purpose: Eliminate redundant encoding of files in the case
         of sending personalized emails to a group of email 
         addresses.
 5/15/02 Paul Keary - Added Jeff Pilant's code to determine TimeZone 
         from the Windows Registry.  Also removed tab characters
         from source code and replaced with spaces. 
 5/23/02 Paul Keary - Fixed bug in doFiles, if the encoded file already
         existed the attachbinlist variable was not be set correctly,
         moved assignment statement outside of do block where
         base64encode is called.
         Added code to not add / to EncodeDirectory if last char is \.
         on Win32 - temp files became C:\TEMP\/filename instead of 
         C:\TEMP\filename.
 8/22/02 Steve Southwell - Added RAW to length() when used to set 
         memptr sizes - Thanks to Rares Stanciulescu     
         Changed "HELO How are you?" to "HELO " followed by the local
         hostname.  Thanks to Bill Prew, David Craven, Scott Ziola, 
         and Hugh Cruickshank   
 9/19/02 Peter Kalmijn - Bug fix for first binary attachment corruption 
         posted to api@peg.com.  Change committed by SES.
 9/24/02 Paul Keary - Added optional capability to set boundary 
         parameter in the MIMEHeader variable.  Used to correct a bug
         Jeff Pilant found when trying to send an html formatted 
         email.  By using boundary=[Boundary] in conjunction with
         type=multipart/mixed (conditional on type value beginning 
         multipart)
12/18/02 Steven L. Jellin - Sorted out problem with multiple recipients
         and CC list.  Instead of just looping through the TO and CC 
         variables, each entry is sent to newstate and removed from 
         the "," separated list. State has been left as 3 until ALL 
         TO and CC entries are completed.
01/02/03 Steve Southwell 
         - Various tweaks to handle multiline SMTP responses and
           incomplete packets.
         - Added additional preprocessors for logging levels
           to avoid having to type "if loglevel < X" everywhere.
           From now on, just use Logger1, logger2, or logger3.  
           Added sanity check on To and CC lists to make sure they 
           get trimmed first.
         - Added ability to specify port number as part of the mailhost
         - Added BCC functionality
         - Added Reply-To functionality (Thanks to Edgar Medrano)
         - Added enhanced error reporting and logging - use
           throwError(errorMessage) 
04/30/03 Paul Keary
         - Read loglevel from file "smtploglevel" if it is found in 
           the PROPATH Allows loglevels to be changed without 
           requiring any recompiling.
         - Added check to see which directory smtpmail.p is located in.
           If THIS-PROCEDURE:FILE-NAME BEGINS "ffw" THEN run the 
           supporting programs also in ffw/procs. This was previously
           handled using the PublicVersion preprocessor. 
         - Cleaned up indentation of some lines in readhandler.
         - Cleaned up the logging messages to be more somewhat more 
           readable.  Changed some of the logging text, changed 
           logging levels of some messages from level-2 to level-1 
           due to detailed nature of the info.
           If loglevel 2 is selected print SMTP commands sent on 
           seperate lines and also server response text on its own
           line. This makes it somewhat easier to see the conversation
           going on between client and server.
           CLIENT:HELO smtpserver
           RESP:250 OK
         - Added code to increment icnt to match the current Recipient.
         - Added NewLine after multi-part MIME header. Peter Kalmijn 
           changed the ~n~n to a ~r~n which caused problems with 
           attachments with some SMTP servers.
05/16/03 Paul Keary
         - Changed newline characters to crlf.
BUG FIX  - Added ELSE statement in the Function getfile to set the last 
           character in the memptr to 0.  Since the size of the 
           memory was 1 character larger than the File being read the
           last character was not being initialized and would result 
           in an extra character showing up sporadically at the end 
           of the file contents.
BUG FIX  - Removed conditional clause on MimeHeader being populated.
           To solve bug where body of message disappears when an 
           attachement was included.  
         - Added debugging feature to save contents of a message to 
           a text file apart from the log file.  This code was helpful
           in verifying where crlf were not being output to the 
           SMTP server.
05/19/03 Laszlo Kohl 
         - Add SMTP authentication support. Only base64 type of 
           authentication is supported 
BUG FIX  - If EmailFrom or EmailTo was ? then smtpmail was hanging
         - If EmailCC was ? then smtpmail was hanging 
         - If Subject was ? then 2914 error ocured          
         - If Body was ? then 2914 error ocured          
06/03/03 Garret Schweitzer
         - Added two new PARAMETERs for Read Receipt and Delivery 
           Receipt on the From address comma delimited seperated 
           by a chr(1) delimiter
         - Changed MIME header to support Read/Delivery Receipts
02/25/03 Derek Marley
         - Added the ability to set the Importance flag for the mail
           header, of the message sent. 
           Valid values include 0 to 3, 1 = HIGH; 3 = Low
10/31/03 David J. Craven
         - Merged several versions together. Started w/ 5.5, 5.6 and added:
           - Garret Schweitzer's read reciept and delivery receipt
           - Laszlo Kohl's SMTP authentication
           - Derek Marley's "Importance Flag"
12/11/03 Laszlo Kohl
BUG FIX  - Eliminated endless loop: when processing emailtoTMP line with
           more than 2 recipients 
06/07/06 Carl Verbiest CCE NV (cvb)
         - Renamed timezone variable V10.1A keyword to timezonestring
         - Added "fake" authentication (solved mail being reported as 
           SPAM by some spamfilters)  
         - Use session:temp-directory for temp- & logfiles.
         - Changed priority and notification based upon RFC2298, RFC1891,
           Network traffic analysis from Exchange server and a lot of
           trial and error.
         - Replace ~n in body by crlf, not yet fixed for body in file 
           (we use unix2dos prior to sending as a work-around)
         - Replace ~n in subject by space

09/08/2007 Tony Benn 
         - Change get-tz procedure to use 'timezone' function for OE10

10/03/2007 Jan Keirse 
         - Change getFile not to return a mempointer but work on 
           mgetfile because it caused a memory leak

02/25/2009 Paul Keary
         - Reformat some of long comments to better fit in 80 columns
         - Add Optional Preprocessor arguments to allow customization
           by including configuration file.
           LOGLEVEL, EncodeDirectory and MAILHUB
         - Check for FILE-INFO-FILE-TYPE = ? in DoFiles
           (INDEX(FILE-INFO:FILE-TYPE,"F") = 0) = NO if FILE-TYPE = ?
         - Removed C_PASSWORD from being output to log
         - After calling dofiles: if vMessage <> "" need to set
           vState = -1 so that Cleanup will output vMessage to the log.
         - Fixed bug with PROCESS EVENTS in OE10 replaced with 
           RUN readhandler.
           Solution from peg.com/lists/freeframework/web/msg00582.html
         - Fixed bug #1447967 related to removal of b64 file when
           DoneWithFiles is called.
         - Fixed bug #2449147 related to cThisLine values
