Filter Improvement
----------------------
	-> Still receiving spam?
	   If you receive spam messages after installing this plugin
	   which are not filtered out just mail the text of the spam message
	   to me and I will integrate some bad phrases out of it immediately.
	   If the filtering of that message can't be done via bad phrases I
	   will try to find another way and integrate that way, too. 
  
	-> New filtering ideas?
	   If you have some other spam filtering ideas please mail me.

	-> Bugs?
	   If you find any bugs please tell them to me via mail.
	   So I don't have to look everywhere around to find them. ;-) 

	-> Patches or Extensions?
	   If you are a developer and/or know how to code
	   feel free to send me patches or extensions to the code.
	   The best way is via e-mail.
	   I really appreciate it. :-) 
	   If you need extensions to the API please contact me, too.

	-> Filtering in all languages?! 
	   There are already bad phrases for the following languages:
	   English, German, French, Russian, Portuguese (Brazil), Chinese (Traditional)
	   I would love it if this list could be extended further.
	   It is a little difficult to speak and understand all languages of this
	   world at the same time ;-) ...and if you speak a language that I don't...
	   (and I think that are very much ;-)...) please send some bad phrases in
	   your language to me.
	   It would be nice if spam could be filtered in all languages,
	   but I need some help... please... :-)
	  Also feel encouraged to release your own Spam Definitions on the File Listing.

	-> Reporting spam log file?!
	   You can also help me via sending your spam log file to me.
	   So I can look for new/better bad phrases.
	   Such a log file can be created with the spam logging feature.
	   It doesn't include any data beside the spam messages sent to you.
	   I will look at it and intergrate some more bad phrases out of it to
	   improve the filter quality.

	-> New bad phrases?
 	   If you have some bad phrases to add to the existing lists
	   please mail them to me, too.
	   I will check the bad phrases and integrate them immediately.

Requirements
----------------------
	-> Miranda IM 0.4.3+:
	Miranda IM is needed in the version 0.4.3 or greater.
	
	-> Popup Plugin 1.0.1.9+ (optional):
	For using the popup function when a spam message
	arrives it is necessary to have the popup plugin installed,
	At least version 1.0.1.9 or greater. 
	PopupPlus is supported, too.
	You need PopupPlus 2.0.3.97 or later.

	-> Variables Plugin 0.2.0.23+ (optional):
	For using variables in outgoing reply messages
	you need to have the Variables Plugin installed,
	At least version 0.2.0.23 or greater. 


Usage
----------------------
	"Spam Filter" options can be found here:
	"Options" -> "Events" -> "Spam Filter"
	
	The sound file which is played when spam arrives can be changed in:
	"Options" -> "Events" -> "Sounds"

	Mark-Read feature:
	If you chose "mark spam messages as read" in the options recommended option)
	the spammer shows up in a half-visible way on your contact list.
	However, the incoming message notification is blocked.
	When you close Miranda IM all half-visible (not-on-list) contacts get removed automatically!

	To avoid the online notification go to the Ignore options and activate "suppress online notification" for unknown contacts.

	If you dislike this behaviour choose "delete spam" (but be aware that you might loose messages).

	Un-Ignoring spammers:
	Recognized spammers can be easily unignored usinf the options.
	Just go to "Options" -> "Events" -> "Spam Filter" and click on the "Spammers" button.
	
	If a unknown user sent you a message and you want to be sure he is no longer watched by the filter, just click
	on "Add user to contact list" in the contact's menu. (This only works if you chose "mark spam as read".)


Spam Definitions
----------------------
	"Spam Definitions" are a set of files which Spam Filter uses to detect spam.
	The files contain well selected words/phrases etc. which a common in spam messages.
	The Spam Definitions are mostly used by the "Advertisment Filter".

	The Spam Definitions make up the default filter behaviour of Spam Filter.
	You normally should not need to modify these files. Instead you should use
	"Options" -> "Events" -> "Spam Filter" to configure your personal filter words.

	You can install as many Spam Definitions as you like, but you should at least 
	install one package in your language.
	The filter will not work as it should without any Spam Definitions.
	For each languge package you install the plugin can filter spam messages.
	For example, if you install the "German" and the "English" packages,
	most German and English spam can be filtered.
	Spam Filter can only filter for those languages it has data sets available.

	Spam Filter loads all Spam Definition Files it can find in the directories.
	All contents of all files are considered when a message is checked for spam.
	Spam Filter does not know which language the message is, it simply compares its contents.

	The exactness and accuracy of Spam Filter depends on its Spam Definitions.
	If the Spam Definitions are not good, the filter is not exact.
	
	The current Spam Definitions can be viewed in
	the "Spam Filter" subdirectory of the Miranda IM folder.

	How it works:
	There are different Spam Definition languages available because Spam Filter needs different data sets
	(e.g. bad words) for the different languages. This is necessary, because bad word filtering consits
	only of testing if a word exists in the message or not.
	When there are enough bad words in the message it will be seen as spam.
	If Spam Filter would only have a list of English bad words (like "earn money",...)
	it would only be able to filter English spam, since the words "earn money", etc do only exist in English messages.
	To filter German spam another data set is needed for the filter with e.g. "Sonderangebot",
	which again probably never will exist in English spam messages.
	The more Spam Definition languages you have installed, the more spam you can filter.

	Spam Filter does not detect the language of a message. It simply loads all bad words it can find
	in the directoriy and checks if any of the contained bad words do match with the message.
	If they match it is spam, if they do not, it is no spam.

	The file names are not important for the filter (only extension and subdirectory is considered). 
	They are named "English", "German", etc so that it is easier to determine what they contain.
	
	Spam Filter checks if any contained word of the Spam Definitions matches with the message.
	It counts how many matches it can find and then checks if the matches are enough to consider the message as spam.

	If you get a spam message in a language for which you don't have Spam Definitions installed, it won't be a problem.
	It won't break anything, nor will your PC be blown up, or sth. like this... ;-) 
	Spam Filter simple won't be able to filter this message. The message will be detected as no spam,
	because there are no data sets available.

	Example:
	If you receive, for example, French spam and you don't have the French Spam Definitions installed.
	Spam Filter will then load all bad words it can find in the Definitions to detect if it is spam.
	But, no matches will be found, because French spam does normally not contain English or German words.
	French spam typically contains French words... ;-)

	Spam for which you don't have any Spam Definitions installed can 
	only be blocked by the Robot Filter (if enabled additionally)
	or if (by chance) the message contains some English bad words, or some common URLs (like .org, .com), etc.
	

Installation
----------------------
	The easiest way to install this plugin is to use the
	installation tool "Miranda Installer" (sadly not available anymore).

	If you don't want to use that tool you can install this plugin
	manually, too.
	Just copy all the contents of the zip-file as they are into the "Plugins" directory
	in the Miranda IM folder.
	"Spam Filter" will detect the files and move them into the appropriate directories
	on it's first run.
	
	You can also do all the installation by hand, if you want to:

	Main Plugin: Copy the file "spamfilter.dll" into the "Plugins" directory
	in the Miranda IM folder. 
	If you would like to use Unicode you need to copy the file "spamfilterW.dll"
	instead. Using Unicode will only work for Windows NT4/2000+.
	  
	Support for Regular Expressions:
	If you would like to use Regular Expressions with Spam Filter (recommended)
	then you should copy the file "pcre.dll" (RegExp DLL) into the Miranda IM directory.

	Spam Definitions: The contents of the "Spam Filter" folder from the zip file,
	including its subdirectories, need to be placed into a new created
	"Spam Filter" subdirectory in the Miranda IM main directory.
	The filter will not work as it should without any Spam Definitions.
	
	Documentation: The txt-files should be moved along with the sdk-zip into the
	"Docs" directory in the Miranda IM folder. 
	
	Sounds: The wav-files should be moved into the "Sounds"
	directory. They will get recognized automatically and be added to the sounds list.

	That's it!


Bugs and Wishes
----------------------
	Feel free to mail me your wishes about "Spam Filter" and tell
	me all the bugs you may find.
	Please tell them to me via mail so I don't have to look
	everywhere around to find them. ;-) 
	My email address is: hrathh at users.sourceforge.net

	# I would love it if you could mail me your translated bad phrases
	   in your language. I would be nice if spam could be filtered in
	   all languages, but I need some help, please... :-)
	   ... Or perhaps you want to add some bad phrases to an existing list?
	   That's also possible... ;-) 

	# If you have any bad phrases that you want to be integrated into
	   the standard bad phrases of the next release of "Spam Filter"
 	   please mail them to me.

	# If you think a string is not grammatically correct or something
	   please mail me, too. (English is not my first language.) 


Filtering Tips
----------------------
	#1:
	WebAware is often used by ICQ spambots,
	if you disable it, you'll not get as many spam as before.
	Goto: Options -> Network -> ICQ Privacy
	
	#2:
	Perhaps the following tip is useful for users that don't use latin letters
	on the system due to their language:

	Tip by ZaNuDa: (thanks very much!)
	"I have a good idea to filter out some of the spam messages sent to me by robots.
	These programs are plain enough and insert in their messages my nick from ICQ registration
	data regardless of my country and native language. My nickname and name is written
	on the ICQ site in transliteration, with latin letters.
	Russian ICQ users writing to me never use these phrases in Latin transcription.
	So I know, that when I receive message beginning with one of these phrases, it is probably
	spam sent to me by a robot. So I've added both phrases to customized the bad phrases list. And it works for me."


To-Do List (random ideas)
----------------------
	- Some events in are not yet Unicode enabled in spam filter  (Miranda unicode event documentaion is quite crappy...not existant)
	
	? Add a main menu item "Show spam log" (initially deactivated) or "Show Spammers", user can enable it
	   on MenuOrder options (currently not possible using menu API of miranda)

	? Button "Recognize this message as a spam" on message dialog
	  so that it will be easier to add patterns to the list without going to the options (suggested by PanTzeR)
	  >> this could show a editbox containing the message content
	  >> after clicking OK the editbox content is added as new bad word/disliked word
	  -> not a good idea IMHO, since bad words should not be taken out of one single message
	  Instead: the option "Mark this contact as spammer" should be used
	  -> MS_SPAMFILTER_SHOWFILTERDIALOG does much of this (show spam filter options)
	  -> message dialog should/could offer support for this
      
	?  Extend the Popup message text to contain more information than just "Advertisment Alert!"
	   -> similar to log file items
	   -> making it customizable  (suggested by Dominik Sebald)
	   -> I don't know if this is really necessary...
	   -> Problem: If the popup contains the mesage text the behaviour is almost the same as without spam filter :-)

	? "Filtered Spam" Window where all filtered messages are displayed (similar to log file, but no separate file)
	  >> The user can choose which one he would like to delete
	  >> and which ones he would like to be put back into the contacts history
	  (better than a "show log file" menu item)

	? Filtering based on user info data, contact details (really necessary?)
	   -> quite difficult, because user details are first available
	       after the first message was received and added to db (for new temporary contacts), only UIN is first available
	   -> Solution: need to watch Nick setting, or wait for proto acks

	? Add filter for SMS Plugin(s)
	   >> (Spam Filter offers spam checking services...
	   >> so the better way would be if the SMS Plugins would support Spam Filter)

	? Add filter for YAMN plugin (e-mail)
	   >> (Spam Filter offers spam checking services...
	   >> so the better way would be if YAMN supports Spam Filter)

	? Bayesian method: -> will probably be "Spam Filter v3" (really necessary? I think it's too much...)
	   >> This feature will be added additionally to the phrase filtering method (-> functioning as expert option)
	   >> Perhaps as an half bayesian filter, which means that spam database will be shared
	   >> and only few people (around 100) are allowed to maintain it
	    - Integrate Bayesian filtering (http://www.paulgraham.com/antispam.html) (thanks to InvisiBill)
	    - Change to percent (%) spam detection: messages declared as
	      spam at 75% spam probability
	   >> Save spam database on server to share the training data
