Summary of the invention
The inventor finds, could download mail in the preservation of mail server side owing to need the user to carry out specific the setting at Mail Clients, has caused the defective that exists mail data possibly can't recover.If abandon this intrinsic scheme, but take directly to preserve the technological means of mail to preset file type, then can not rely on user's specific setting, the effectively fail safe of certified mail, and the follow-up mail that can come out to avoid the Mail Clients repeated downloads to download according to the mail sorting that default file type has been downloaded Mail Clients.
After having introduced basic principle of the present invention, following mask body is introduced various non-limiting execution mode of the present invention.
The application scenarios overview
At first with reference to figure 2, as shown in Figure 2, the adaptable scene of embodiment of the present invention can be for comprising the email distribution and reception system of mail server 201 and Mail Clients 202, wherein the communication protocol between mail server 201 and the Mail Clients 202 can be that POP3 agreement or other are applicable to agreement of the present invention, does not limit in the present invention.
Illustrative methods
Below in conjunction with the application scenarios of Fig. 2, be described with reference to Figure 3 the method in the execution of mail server side according to exemplary embodiment of the invention.It should be noted that above-mentioned application scenarios only is to illustrate for the ease of understanding spirit of the present invention and principle, embodiments of the present invention are unrestricted in this regard.On the contrary, embodiments of the present invention any scene that can be applied to be suitable for.
Referring to Fig. 3, one of a kind of method flow schematic diagram of carrying out in the mail server side that provides for the embodiment of the invention, as shown in the figure, this method embodiment can comprise:
S310, in response to receive to download the finish command from Mail Clients, whether inquiry exists mail to be deleted;
If S320 determines to exist mail to be deleted, this is waited to delete mail preserve with default file type.
Use the method for the above embodiment of the present invention, mail server can initiatively not collected mail the user and kept copy under the situation of the specific setting on the server, initiatively the mail that Mail Clients has been downloaded is preserved with default file type, do not rely on user's specific setting, when the mail data of Mail Clients damages, can recover the mail downloaded from mail server, effectively guarantee the fail safe of mail.And follow-up can the differentiation according to default file type waits to delete mail and other mails, may for avoiding Mail Clients repeated downloads mail to provide.As seen, the method for the above embodiment of the present invention does not need the user to do any setting at Mail Clients, is all automatically performed by mail server, has significantly improved the fail safe of mail.
Wherein, default file type is mainly used in distinguishing waits to delete mail and other mails, distinguishes mail according to default file type, can avoid Mail Clients repeated downloads mail.For example, referring to Fig. 4, two of a kind of method flow schematic diagram of carrying out in the mail server side that provides for the embodiment of the invention, as shown in the figure, this method embodiment can comprise:
S410, in response to receive to download the finish command from Mail Clients, whether inquiry exists mail to be deleted;
If S420 determines to exist mail to be deleted, this is waited to delete mail preserve with default file type;
S430, according to the order of Mail Clients inquiry mail the time, skip over the mail of preserving with default file type.
The difference of the execution mode that this is shown in Figure 4 and execution mode shown in Figure 3 is, when this embodiment can also be included in according to the order inquiry mail of Mail Clients, skip over the step of the mail of preserving with default file type, can avoid Mail Clients repeated downloads mail according to this execution mode.
Usually pass through the relevant information realization of data-base recording mail to the management of mail in conjunction with mail server, when inquiring about mail according to the order of Mail Clients, can skip over the mail of preserving with default file type according to the information of data-base recording.For example, referring to Fig. 5, three of a kind of method flow schematic diagram of carrying out in the mail server side that provides for the embodiment of the invention, as shown in the figure, the information of data-base recording comprises the folder information related with user ID at least among this embodiment, can comprise:
S510, in response to receive to download the finish command from Mail Clients, whether inquiry exists mail to be deleted;
If S520 determines to exist mail to be deleted, this is waited to delete mail preserve with default file type;
S530, according to the order of Mail Clients, determine user ID;
According to the POP3 agreement, the order of Mail Clients for example can comprise, the LIST(mail tabulation) order, for the treatment of the size of returning number of mail and each mail; RETR(fetches mail) order, for the treatment of the text that returns by the mail of mail sign (ID), perhaps other orders etc.The user ID that is used for determining user account has all been carried in these orders.
The folder information related with this user ID in S531, the Query Database judges that whether the folder information related with this user ID be the folder information with default file type sign;
S532, if not feeds back to Mail Clients according to this document folder information;
S533 is if skip over this document folder information.
Again particularly, for example, use above-described embodiment, LIST or RETR order inquiry mail according to Mail Clients, then described folder information also should comprise the store path of file correspondence, if the folder information related with this user ID is not the folder information with default file type sign, then can press from both sides information according to this document, from folder information, extract the corresponding store path of this document folder, read out mail tabulation or mail document under the described store path again, feed back this mail tabulation or mail text to Mail Clients.
In embodiments of the present invention, in order to distinguish mail to be deleted, reach and delete the purpose that mail is preserved with default file type with waiting, mail to be deleted can be moved to the file with default file type sign.At other mails of follow-up transmission, perhaps treat the deletion mail when operating, can whether be the file of default file type sign according to mail actual storage locations place file, distinguish mail to be deleted.For example, if definite existence mail to be deleted of the embodiment of the invention is waited to delete mail with this and can be comprised with the step of presetting the file type preservation:
If determine to exist mail to be deleted, whether inquiry exists the file with default file type sign;
If there is no, create the file that identifies with default file type;
This mail to be deleted is moved to the file that identifies with default file type.
And/or,
In conjunction with the database information that mail server is set up for the management mail, can reach equally and distinguish mail to be deleted, will wait to delete the purpose that mail is preserved with default file type.For example, the information of data-base recording can comprise that mail server is the unique mail ID, the information relevant with mail ID, for example incidence relation of the incidence relation of mail ID and delete flag, mail ID and file ID that are used for the expression mail that every envelope mail arranges.As according to the POP3 agreement, when Mail Clients receives mail, can send the DELE order to mail server, mail server side is according to the parameter of DELE order, can also in database, record the incidence relation of mail ID and delete flag, make mail be labeled as deletion.Receive download the finish command that Mail Clients sends at mail server, after the QUIT order, can whether exist according to the information inquiry of data-base recording and the related mail ID of delete flag, wherein, the information of described data-base recording comprises the incidence relation of incidence relation, mail ID and the file ID of delete flag and mail ID at least;
Correspondingly, if definite existence mail to be deleted of the embodiment of the invention is waited to delete mail with this and can be comprised with the step of presetting the file type preservation:
If determine there to be the mail ID related with delete flag, the file ID of this mail ID association is revised as the file ID that identifies with default file type.
Need to prove that the mail ID corresponding mail related with delete flag is stored on the mail server in fact.As seen, the file ID of this mail ID association being revised as file ID with default file type sign has reached and will wait to delete the purpose that mail is preserved with default file type.At other mails of follow-up transmission, perhaps treat the deletion mail when operating, can distinguish mail to be deleted according to the corresponding relation of the default file type that in database, records and mail ID.Therefore, mail to be deleted is not limited under the file ID corresponding file folder that necessarily is stored in default file type sign.
But, be understandable that, for the ease of the Mail Server Management mail, fast read mail, optimize the email storage structure, can be with above-mentioned two kinds of method combinations, for example, referring to Fig. 6, four of a kind of method flow schematic diagram of carrying out in the mail server side that provides for the embodiment of the invention, this method embodiment can comprise:
S610, in response to receive to download the finish command from Mail Clients, whether inquire about in database and exist and the related mail ID of delete flag, the information of described data-base recording comprises the incidence relation of incidence relation, mail ID and the file ID of delete flag and mail ID at least;
If S620.1 determines to exist and the related mail ID of delete flag, whether inquiry exists the file with default file type sign;
For example, whether the folder information related with this user ID comprises default file type sign in can Query Database, if, then show the file of having created default file type sign for this user, and needn't create the file of this default file type sign afterwards for this user again.
S620.2, if there is no creates the file with default file type sign;
For example, for the ease of utilizing database mail is managed, can also be in database recording user ID and the incidence relation with the file of default file type sign that should newly create, and record the store path of the file of this default file type sign.
S620.3, this mail to be deleted is moved to file with default file type sign; And,
If determine there be the mail ID related with delete flag in S620.4, the file ID of this mail ID association is revised as the file ID that identifies with default file type.
In addition, to the file operation that default file type identifies the mail of wherein preserving is lost for fear of Mail Clients, wherein the file of default file type sign can be system folder, and the title of file can be system's reserved name.In order to limit Mail Clients to the operation of the file of default file type sign, the embodiment of the invention can also comprise:
When the operational order that receives from Mail Clients file, according to the operational order to file, determine whether this document folder is the file of default file type sign;
If, to Mail Clients feedback refusal operation information;
If not, according to the operational order to file, carry out the operation to file, wherein, can comprise operations such as establishment, rename, deletion to the operation of file.
Because the mail under the file of default file type sign can not send to Mail Clients, for the user is managed the mail under the file of default file type sign, mail server allows the user by the WEB mailbox mail under the file of default file type sign to be managed, for example:
Mail server can receive the operation requests to the mail in the file of default file type sign, judge whether this operation requests comes from the WEB mailbox, if not, refuse described operation requests, if, according to described operation requests, carry out the operation to the mail in the file of default file type sign.Wherein, the operation to the mail in the file of default file type sign can comprise inquiry, read, move, operation such as deletion.
Wherein, judge whether this operation requests comes from the WEB mailbox, the agreement that comprises identification information in the time of can following WEB mailbox connection mail server in the log messages, whether this login of identification information judgment that comprises according to log-on message is the WEB login, and this identification information can be set according to implementing needs in advance.
Consider that the mail server stores space is limited, also should regularly remove the mail of the overlong time of preserving under the file of default file type sign, to discharge the memory space of mail server, for example:
Can record the time of origin that mail to be deleted moves to the file of default file type sign, for example, the incidence relation of time of origin and mail ID can be recorded in the database;
When described time of origin surpasses default duration apart from the current time, from the file of default file type sign, delete this mail to be deleted.
Wherein said default duration can be the default duration of system default, also can be by the default duration of user by the WEB postbox installment, does not limit in the present invention.For example, the incidence relation that can also comprise default duration and mail ID or user ID in the described database, when timer when default duration triggers inspection to overtime mail, from database, read out the time of origin of each mail ID association, and related default duration, again at each mail ID, calculate the difference that current time subtracts the time of origin of this mail ID association, if difference is greater than default duration, from database, inquire the store path of this mail ID association, with the mail deletion of this mail ID sign under this store path.
Move to the file of default file type sign when mail to be deleted after, in order to make the user understand the state that mail is backed up by all means, the embodiment of the invention can also be after mail to be deleted moves to the file that identifies with default file type, produce message informing, for example following first delete the letter notice, second deletes letter notice and the 3rd deletes the letter notice, with this message informing and other relevant informations, as user ID etc., put into message queue, every default notice duration, whether there is new message notification in the query messages formation, if exist, message informing is taken out from formation, message informing is write message sends file, perhaps according to default contact method (as, email address or phone number etc.) send to the user, particularly, for example:
(1) if mail to be deleted moves to the file with default file type sign, according to default contact method, sends first to the user and delete the letter notice;
For example, according to default contact method, to the user send first delete the letter notice can comprise to default email address send mail, to implementations such as default phone number transmission notes.Wherein, default contact method can be arranged by the WEB mailbox by the user, after mail server receives the request that contact method be set of user by the transmission of WEB mailbox, in the data-base recording that contact method is recorded in this user profile is associated that this is default, and then by Query Database, obtain the contact method with user's corresponding preset.
