referring to fig1 , there is shown a diagram of various networked computer systems 100 in communication with one another via a communications network 106 . it is to be expressly understood that the various computer systems 100 are merely some implementations of the present technology . thus , the description thereof that follows is intended to be only a description of illustrative examples of the present technology . this description is not intended to define the scope or set forth the bounds of the present technology . in some cases , what are believed to be helpful examples of modifications to computer systems 100 may also be set forth below . this is done merely as an aid to understanding , and , again , not to define the scope or set forth the bounds of the present technology . these modifications are not an exhaustive list , and , as a person skilled in the art would understand , other modifications are likely possible . further , where this has not been done ( i . e . where no examples of modifications have been set forth ), it should not be interpreted that no modifications are possible and / or that what is described is the sole manner of implementing that element of the present technology . as a person skilled in the art would understand , this is likely not the case . in addition it is to be understood that the computer systems 100 may provide in certain instances simple implementations of the present technology , and that where such is the case they have been presented in this manner as an aid to understanding . as persons skilled in the art would understand , various implementations of the present technology may be of a greater complexity . the computer systems 100 shown in fig1 are those that interact with a web - based mail service such as yandex ™ mail ( available at mail . yandex . com ). in a web - based mail system , there is typically no dedicated e - mail client on a user &# 39 ; s computer 108 . the user will typically access the mail service via a web - browser on their computer 108 . the web - based mail system 100 is implemented via several clusters of servers : mail delivery server cluster 110 , junk - protection and e - mail classification server cluster 112 , web - mail interface back - end server cluster 114 , web - mail interface front end server cluster 116 , and e - mail storage server cluster 118 . in respect of the web - based mail system 100 , the mail delivery server cluster 110 acts as a mail transfer agent and transfers e - mail messages to and from the mail transfer agents ( e . g . 102 and 104 ) of other e - mail systems . the junk - protection and e - mail classification server cluster 112 implements junk e - mail filtering and e - mail message classification in respect of e - mail received by the system 100 . the web - mail interface back end server cluster 114 is the main engine behind the system 100 . that cluster , for example , implements all of the functions that the users of the system 100 may require , such as managing e - mail messages ; managing the users &# 39 ; mailboxes , folders and subfolders ; managing the users &# 39 ; e - mail account settings , etc . the web - mail interface front end server cluster 116 implements the interaction between the user &# 39 ; s computer 108 and the web - mail interface back end server cluster 114 . the e - mail storage server cluster manages the databases ( meta - data database 120 and message database 122 ) necessary for the web mail system to function . in one embodiment , a “ pre - processing model ” is implemented with regard to e - mail message classification . in a pre - processing model , e - mail is categorized prior to its being delivered to the recipient &# 39 ; s inbox . the steps in such a model are as follows : an e - mail is sent by an external mail transfer agent 102 to the mail delivery server cluster 110 . the e - mail message is received by the mail delivery server cluster 110 . the mail delivery server cluster 110 processes the incoming e - mail message and sends it to the junk e - mail protection and e - mail classification server cluster 112 . the junk e - mail protection and e - mail classification server cluster 112 first makes a determination whether the e - mail message is junk e - mail . if the e - mail message is junk e - mail the junk e - mail protection and e - mail classification server cluster 112 does not make a determination of a classification of the e - mail message . if the e - mail message is not junk e - mail the junk e - mail protection and e - mail classification server cluster 112 proceeds to make a determination of the e - mail message &# 39 ; s sender type and message type ( s ). the e - mail message is sent by the junk e - mail protection and e - mail classification server cluster 112 to the web - mail interface back - end server cluster 114 . the back - end server cluster 114 processes the e - mail message according to the determinations having been made by the junk e - mail protection and e - mail classification server cluster 112 and saves the e - mail message in the e - mail storage databases ( meta - data database 120 and message database 122 ) which are maintained by the e - mail storage server cluster 118 . ( in this embodiment , the body of the message is stored in the message database 122 , while the metadata related to the message is stored in meta - data database 120 . the metadata includes information related to whether the e - mail is junk e - mail and the classification of the message .) in another embodiment , a “ post - processing model ” is implemented with regard to e - mail message classification . in a post - processing model , e - mail is categorized after its having been delivered to the recipient &# 39 ; s in - box ( and in one embodiment only after the recipient has requested that the e - mail be opened ). the steps in such a model are as follows : ( 1 ) an e - mail is sent by an external mail transfer agent 104 to the mail delivery server cluster 110 . ( 2 ) the e - mail message is received by the mail delivery server cluster 110 . the mail delivery server cluster 110 processes the incoming e - mail message and sends it to the web - mail interface back - end server cluster 114 . the back - end server cluster 114 processes the e - mail message and saves the e - mail message in the e - mail storage databases ( meta - data database 120 and message database 122 ) which are maintained by the e - mail storage server cluster 118 . ( as was the case with the previous embodiment , in this embodiment , the body of the message is stored in the message database 122 , while the metadata related to the message is stored in meta - data database 120 .) at some later point in time , the recipient ( user ) accesses the e - mail system via a browser on user &# 39 ; s computer 108 . the browser on user &# 39 ; s computer 108 interacts with web - mail interface front - end server cluster 116 , which provides the user with an interface with which the user can interface with the system . while web - mail interface front - end server cluster 116 provides the user with the interface , the actual mail data ( e . g . the user &# 39 ; s inbox message listing ) is provided by the web - mail interface front - end server cluster 116 after having been received from the web - mail interface back - end server cluster 114 . web - mail interface front - end server cluster 116 thus queries web - interface back - end server cluster 114 for this data . upon receipt of the query from the web - mail interface front - end server cluster 116 , web - mail interface back - end server cluster 114 , communicates with the e - mail storage server cluster 118 , which retrieves the e - mail data from the meta - data database 120 and message database 122 , and forwards it to the web - mail interface back - end server cluster 114 . web - mail mail interface back - end server cluster 114 receives the data and forwards it to the junk protection and e - mail classification server cluster 112 . junk protection and e - mail classification server cluster 112 makes a determination as to whether the e - mail messages having been forwarded to it are junk e - mail . for those e - mail messages that are junk e - mail no categorization takes place . for those e - mail messages that are not junk e - mail messages , the junk protection and e - mail classification server cluster 112 determines the sender type and message type ( s ) for each message . the determinations of the junk protection and e - mail classification server cluster 112 are then sent back the web - mail interface back - end server cluster 114 which processes the determinations made by the junk protection and e - mail classification server cluster 112 and forwards all necessary data and information to both the web - mail interface front end server cluster 116 ( for display to a user ) and the e - mail storage server cluster 118 for saving in the meta - data database 120 and the message database 122 as appropriate . to illustrate the functioning of the system , by way of example several sample e - mail messages are reproduced below and the assignment of a message type to each is provided . it should be understood that these examples are merely for the purposes of illustration and have been simplified for that purpose . the user d . cathy0007 @ gmail . com on the site ria . ua has left you a message in response to your ad for “ samsung notebook 300u1 ”: to see your ad page please go to the following link : this message is not spam under the ukraine law no . 720 ( telecommunications ) in one embodiment , sample e - mail one would be assigned a message type of “ notification ” for the following reasons : the link “ click here to unsubscribe ” contains a linked url in the form “ unsubscribe ” or “ opt - out ”. the character string “ message ” is present in the body of the e - mail . at least one of the following character strings : “ personally ”, “ private ”, “ to you ”, “ received ”, “ for you ”, “ you have ”, “ unread ”, “ new ” is found in the same sentence as the character string “ message ” in the e - mail . the “ subject ” header field does not contain character string “ re :” nor the character string “ fwd :” the message does not have a message type “ bounce ”. the aforementioned reasoning , when converted into elementary rules ( er - ex1 -#) and complex rules ( cr - ex1 -#) in accordance with an embodiment of the present technology would appear as follows : er - ex1 - 1 : does the body of the message contain a link containing the character string “ unsubscribe ”?

s inbox of the yandex ™ webmail e - mail service showing an embodiment of the present technology . in the inbox there is an e - mail message listing in which information about e - mails having been received is shown . information about message 202 is shown in a conventional format using information extracted from that e - mail message &# 39 ; s header . thus there is shown the name 204 of the sender of e - mail message 202 ( from the e - mail &# 39 ; s from header field ), the subject 206 of the e - mail message 202 ( from the e - mail &# 39 ; s subject header field ), the time 208 of e - mail message 202 ( from the e - mail &# 39 ; s date header field ). message 210 however is shown in non - conventional manner as the result of the present technology . a message type of message 210 has been determined to be “ ticket ” by the present technology . in this embodiment , information is extracted from the content of the body of the message 210 ( via regular expressions , etc .) and has been presented in the e - mail message listing in a standardized format appropriate ( in this embodiment ) for the message type “ ticket ”. thus , notwithstanding the then current view ( in terms of which e - mail header items are to be displayed for each e - mail item ), the following information regarding message 210 is instead displayed in the e - mail message listing : the outbound flight number 212 ( flight no . nn - 658 ); the departure city , date , and time 214 ( moscow , august 20 , 11 : 20 pm ); the return flight number 216 ( flight no , nn - 659 ); the return city , date , and time 218 ( amsterdam , august 24 , 7 : 40 pm ). in this embodiment , information has also been extracted from an external internet resource ( i . e . the airline klm &# 39 ; s website ) in the form of the airline klm &# 39 ; s logo 220 and has been presented in the e - mail message 210 listing . the klm logo 220 is also a widget in that clicking on the logo by the user will take the user to the airline klm &# 39 ; s website in the user &# 39 ; s web browser . the time 224 of the e - mail message 210 ( from the e - mail &# 39 ; s date header field ) is also displayed , along with a print 222 functionality . referring to fig3 , there is shown a partial screen shot 300 of a user &# 39 ; s email message reading pane of the yandex webmail e - mail service showing another embodiment of the present technology . in fig3 , the user is viewing the actual e - mail message 210 shown in fig2 . the e - mail viewing pane has been modified in view of the present technology . the viewing pane shows the e - mail &# 39 ; s header information 302 and the body 304 of the e - mail . however the e - mail has also been reformatted in accordance with the present technology . in this respect , certain information has been extracted from the body 304 of the e - mail and is displayed at the top of the viewing pane in a standardized format ( according to this message &# 39 ; s message type “ ticket ”). in this respect , at the top of the viewing pane there is displayed the following information : the outbound flight number 308 ( flight no . nn - 658 ); the departure city , date , and time 310 ( moscow , august 20 , 11 : 20 pm ); the return flight number 312 ( flight no , nn - 659 ); the return city , date , and time 314 ( amsterdam , august 24 , 7 : 40 pm ). a widget 316 allowing the user to be reminded of this information ( i . e . the flight information ) at the appropriate times has been added , as well as printer functionality 318 . referring to fig4 , there is shown a partial screen shot 400 of a user &# 39 ; s email message reading pane of the yandex webmail e - mail service showing another embodiment of the present technology . the e - mail viewing pane has been modified in view of the present technology . the viewing pane shows the e - mail &# 39 ; s header information 402 and the body 404 of the e - mail . however the e - mail has also been reformatted in accordance with the present technology . in this respect , certain information has been extracted from the body 404 of the e - mail and is displayed at the top of the viewing pane in a standardized format ( according to this message &# 39 ; s message type “ invitation ” and sender type “ individual ”). in this embodiment , the message type “ invitation ” is determined for the sender type “ individual ” when the user has been invited by an individual to an event . the e - mail system extracts information about the event to which the user has been invited ( via regular expressions , etc .) from the header 402 and the body 404 of the message and provides the user with that information in a standardized format ( according to this message &# 39 ; s message type and sender type ). in this respect , at the top of the viewing pane there is displayed the following information : a statement 408 that the user has been invited to an event by the sender ( with the sender being named by name ); the date and time 410 of the event ; and the address 412 of the event . in this embodiment , response widgets 412 and 414 have also been provided to the user . were the user to click on affirmative response widget 412 , the user would be provided with a ready - to - send e - mail stating that they will attend the event ( the user could modify the e - mail if they so choose to do before sending ). were the user to click on the negative response widget 414 , the user would be provided with a ready - to - send negative e - mail stating that they will not attend the event ( the user could modify the e - mail if they so choose to do before sending ). it should be understood that the message in this case is not an e - mail event invitation in a standard form created by conventional e - mail clients . the message is simply an e - mail from one person to another asking if they would like to join them at an event . referring to fig5 , there is shown a partial screen shot 500 of a user &# 39 ; s email message reading pane of the yandex webmail e - mail service showing another embodiment of the present technology . the e - mail viewing pane has been modified in view of the present technology . the viewing pane shows the e - mail &# 39 ; s header information 502 and the body 504 of the e - mail . this e - mail message is a message from the discount service groupon ™ providing the user with offers regarding certain products and / or services . ( such e - mails are a standard part of the groupon service offering .) the e - mail has also been reformatted in accordance with the present technology . in this respect , a widget 506 is displayed at the top of the viewing pane in a standardized format ( according to this message &# 39 ; s message type “ discountservice ”). in this embodiment , the message type “ discountservice ” is determined when the user receives an e - mail from a discount service provider offering them goods and / or services for purchase . in this embodiment , the e - mail system determines ( via regular expressions , etc .) what the general category is of the particular goods and / or services being offer to the user in this particular e - mail is . ( the general categories having been previously programming into the system .) the first time that the system encounters such an e - mail ( of the message type “ discount ”)— as is the case in the e - mail shown in the fig5 , the system provides a widget asking the user which kinds of e - mails that the user wants to see from discount services . in particular , which general categories of particular goods and / services the user wants to see e - mail about and which the user does not . in this respect , widget 506 provides user with a series of check boxes 510 each associated with general category of goods and / or services that the system is capable of identifying . the user can check the boxes 510 for those categories of goods and / or services for which they want to receive information ( e . g . receive e - mails ) and leave unchecked the boxes 510 for those categories of goods and / or services for which they do not want to receive information . the user then clicks a button 512 in the widget 506 and the system stores the information . from that point forward ( until the user modifies their settings in this respect ) the system will only place into the user &# 39 ; s inbox e - mails from discount services ( in this example ) wherein the goods and / or services being offered in that particular e - mail fall within a category of goods and / or services for which the user has requested to be provided with e - mails . e - mails offering goods and / or services other than goods and / or services for which the user has requested to be provided with e - mails will automatically be placed by the system into the user &# 39 ; s deleted items folder . in this embodiment , at any time the user chooses to do so , they may modify the system &# 39 ; s settings by going into the settings menu , where they can check and / or uncheck boxes as they so desire . this procedure can be implemented for any number of types of services ; it is not limited to discount services . modifications and improvements to the above - described implementations of the present technology may become apparent to those skilled in the art . the foregoing description is intended to be exemplary rather than limiting . the scope of the present technology is therefore intended to be limited solely by the scope of the appended claims .
