Changes, Fixes, New Features and Enhancements by Wildcat! Component   



WCCONFIG (Wildcat! Configuration)


- ENH: Expanded directory selection browse window for file areas
       and other similar sections.

- NEW: New Remote Mail Hosts configurations allows for using Authentication,
       Port 587 and TLS for outgoing messages.


WCT (Wildcat! Templates)


- Fixed persistent frames issue with personal properties.

- NEW: New LET macro

  The LET macro is designed to be use when using WCT functions such as
  SPLIT, MID, etc.

  @SET v1 = "p1,p2,p3,p4"@
  @LET v1 = split(v1,",")@

- NEW New WCT function macros

  Conditional WCT macros

  @SET var = IF(p1, p2, p3)@
  @SET var = IFSET(p2, p2, p3)@
  @SET var = IFEXIST(p1, p2, p3)@

    IF

    if the p1 value is exist and is true, a positive number or a string,
    then return p2 otherwise p3

    IFSET

    if the p1 value is exist (has any value) then return p2 otherwise p3

    IFEXIST

    if the file p1 exist, then return p2 otherwise p3


  String functions:

  @SET var = MID(p1,p2,p3)@
  @SET var = LEFT(p1,p2)@
  @SET var = RIGHT(p1,p2)@
  @SET var = SUBST(p1,p2,p3)@
  @SET var = ISUBST(p1,p2,p3)@    case insensitive subst
  @SET var = LCASE(p1)@
  @SET var = UCASE(p1)@
  @SET var = TRIM(p1)@
  @SET var = SPLIT(p1,p2 [,p3])@

  These string functions are functionality equivalent to the WCBASIC counterparts.

  SPLIT is WCT only and provides a way to create a WCT array. For example:

  @SET names = "charlie, sam, jose"@
  @SET names = split(names,",")@

  here, we wish to split the names variable by comma into an indexed array.

  The resultant variables in memory are:

      names        = "charlie, sam, jose"
      names.count  = 3
      names[1]     = "charlie"
      names[2]     = "sam"
      names[3]     = "jose"

  Now its possible to use the FOR loop to display them:

  @FOR I=1 to NAMES.COUNT@
     @SUB NAMES[{i}]@
  @NEXT@

  Math functions:

  @SET var = MULT(p1,p2)@       Multply p1 with p2
  @SET var = DIV(p1,p2)@        Divide p1 by p2


- FIX: Fixed the GetFileByXXXX macro for initial no file found search result.


WCSAP (Wildcat! Sender Authentication Protocol)


- ENH: Added a lookup cache for macro %HDN% to avoid redundant lookups.

  When using the %HDN% macro, this performs a reverse DNS (PTR query)
  lookup for the connection IP address. So using multiple rules
  (reject/accept) such as:

    reject if %HDN% in *.tr
    reject if %HDN% in *.bg
    reject if %HDN% in *.co
    reject if %HDN% in *.co*.th
    reject if %HDN% in *.lk
    reject if %HDN% in *.ru

  would do a redundant %HDN% lookup for each rule.  If the PTR record did
  not exist in DNS, this would degrade wcsap filtering performance.

  The %HDN% result is now cached so that the subsequent %HDN% lookups
  are remembered.  This greatly speeds up processing all the %HDN% based
  rules.


WCNODE (Wildcat! Node)


- ENH: WCNODE now also accept common /SERVER:xxxxxx for server name.


WCMAIL (Wildcat! MAIL)


- NEW: Optional Date subfolders under the SPOOL "DONE" folder.

  If the option under mail host is disabled:

     [_] Delete files after processing

  Then imported local email will be saved in the SPOOL\{host}\DONE folder.

  While normally this option is only used for temporary analysis of mail
  as it was received and imported, if enabled, the DONE folder will accumulated
  a large set of *.D/*.X

  A new registry option allows you to separate this DONE storage using a date
  format.  To use this, create a WCMAIL registry called:

      SpoolDoneDateFormat:  format

  where format can be:

    {yyyy}
    {yy}
    {mm}
    {dd}
    {hh}
    {ss}

  Example value:  {yyyy}-{mm}-{dd}

  If today is July 24, 2010, this will store the processed file in

     spool\{hostname}\done\2010-07-24

- FIX: Fixed a Bouncing Issue with invalid local user return paths


WCSMTP (Wildcat! SMTP)


- NEW: New Remote Mail Hosts configurations allows for using Authentication,
       Port 587 and TLS for outgoing messages.

- NEW: Support for DSN (Delivery Status Notification) formatted bounces.

  WcSMTP will now use RFC 3464 Delivery Status Notification (DSN) to
  create bounce messages.

  If you wish to use the original text-based only Bounce format, you can
  disable the option by adding a registry value for wcSMTP.  You can use
  WCREGEDIT for this:

  DISABLE:

  wcregedit /local /value:wcsmtp\EnableDNSReports /dword:0

  RE-ENABLE:

  wcregedit /local /value:wcsmtp\EnableDNSReports /dword:1

  Why use DNS?

  No real reason other than its is a formal industry standard which
  basically provides structured details for the bounce and also puts the
  original message as an attachment.

  As before, the actual notification bounce text message readable by
  humans is still the same, but there  will be now additional
  information useful for diagnostics.

- FIX: Fixed a Bouncing Issue with invalid local user return paths

- NEW: Added Local Blowback Protection

  When a return path address using a local domain (you own it) is used
  for the MAIL FROM: address, wcSMTP will now validate the existenance
  of the userid in the address.

  This new feature helps protected against unnecessary bounces when
  mail can not be delivered to target recipients which will naturally
  create bounces back to the return address (MAIL FROM).  However, if the
  return path is invalid on your system, this created another bounce to
  no where. This features will enforce a valid local domain return path.

  If this new feature is causing problems (which it should not because
  allowing invalid local domain return path will discard any non-delivery
  notifications), you can turn it off using the registry option:

    wcregedit /local /value:wcsmtp\checklocalreturnpath /dword:0

  To reenabled the option:

    wcregedit /local /value:wcsmtp\checklocalreturnpath /dword:1

  Note: You should always make sure you are using a valid return path
  (MAIL FROM) in your email send mail tools.  Not having a valid return
  path will discard notifications and can potentially give you a bad
  negative reputation on other remote mail servers rejecting your mail.
  It is always good practice to have a valid return path address.

- NEW: New SMTP session commands

  SMQ               - Show the Mail outbound Queue
  SHOW STATS        - Show the statistics on the WCSMTP machine

- ENH: 2nd WCSMTP instances can now run on seperate computers

  WCSMTP can now be "scaled out" to better load balance email
  operations.  This can only work correctly when using different
  computers.

  You can use a shared folder from the main computer, i.e, Z:\WCAT,
  where you have Wildcat! installed where Z is a mapped drive.

  Or you can create a local machine directory for wcsmtp, i.e, c:\WCSMTP

  When done this way, the following of the minimum required files that
  are put into the directory created:

     wcsmtp.exe
     wcsrv2.dll
     wccore.dll
     wcdns.dll
     wciphlpapi.dll
     wcsgate.dll
     wcsmtpft.dll

  The following DLL "May" be required if you have SMTPFILTER WCX applications
  that require them:

     wcodbc.dll

  The main reason for using a local machine directory for wcSMTP is when
  you wish to install WCSMTP on the local machine as a NT Service. The
  log files will be separated at this point.


- ENH: Improved WCSMTP NT Service Logging

  - wcsmtp.log now shows the MAIN thread tag when running as a service.
  - wcsmtp.log startup info was enhanced.
  - additional startup error reporting

    Service error 102 - error switching to WCSMTP.EXE path
    Service error 203 - failed to find wcserver to connect to
