In embodiment, it can also only retain the envelope rough draft mail of uplink time the latest, to avoid the limited storage space of terminal device
When, the excessive rough draft mail of version additionally takes its memory space.
Fig. 5 is refer to, is the flow chart for the step S201 that the embodiment of the present application two is provided.As seen from Figure 5, step S201 is also
It may include steps of：
Step S2011：After mobile terminal preserves or updated rough draft mail, it will be needed in the scratch file folder of mobile terminal
Rough draft mail that will be synchronous is set to state to be uploaded.
The scratch file of mobile terminal presss from both sides to be used for the file for depositing rough draft mail, this implementation in mobile terminal data storehouse
Example in mobile terminal scratch file folder be with respective mail server scratch file folder be correspondingly arranged can synchronous documents
Folder.Only when mobile terminal detect its scratch file folder folder attribute for can synchronization folder when, just allow to perform text
The simultaneously operating of part folder, the scratch file folder of the scratch file folder of mobile terminal and mail server is synchronized.
In addition, the present embodiment can be by setting the upload attribute of rough draft mail, to realize that rough draft mail uploads state
Setting.The upload attribute of rough draft mail includes true and false two types, when mobile terminal detects the upload of rough draft mail
When attribute is labeled as true, you can the rough draft mail is judged as state to be uploaded, so as to by further simultaneously operating, will locate
In state to be uploaded rough draft mail synchronization to mail server；When mobile terminal detects the upload attribute mark of rough draft mail
During for false, that is, can determine that the rough draft mail is non-upload state, it is not necessary to which the rough draft mail is synchronized.
In the present embodiment, in order to distinguish the significance level of rough draft mail, mobile terminal can also be by important mark come area
Divide common rough draft mail and important rough draft mail.Important mark can be embodied in the mailbox client of mobile terminal, specifically
It can be the mark of red flag, starlike mark and other shapes and form.E-mail address user can be according to actual needs
Judge important rough draft mail, such as, can be need to continue to edit in other clients or addition annex in be uploaded
The rough draft mail or confidentiality of state are higher, are merely able to the rough draft mail in mobile terminal editor.
Step S2012：According to default synchronizing frequency, whether at least deposited in the scratch file folder for detecting the mobile terminal
The rough draft mail of state to be uploaded is in an envelope.If be at least in the scratch file folder of the mobile terminal in the presence of an envelope
The rough draft mail of state to be uploaded, then perform step S2073.
In the present embodiment, synchronizing frequency is set to real-time synchronization, that is, continues to monitor the upload attribute of rough draft mail, to contract
The synchronizing cycle of short grass original text mail.The mobile terminal difference maximum with PC ends is that mobile terminal is not real-time in the application
Online.Under normal circumstances, ability turn-on data business service is (such as only when mobile terminal user needs to access network
GSM/GPRS is serviced), and the rough draft mail synchronization that will be stored in mobile terminal is undoubtedly needed at mobile terminal to mail server
In presence, therefore, in order to reach the effect of real-time synchronization, it is necessary to which mobile terminal is in presence in real time, easily excessively
The electricity of mobile terminal is consumed, and easily produces extra expenses of surfing Internet.
In actual application situation, E-mail address user may edit an envelope rough draft postal in outdoor application mobile terminal
Part, but need to return it is indoor, using the annex that PC ends add file is larger, in this case, rough draft mail synchronization it is ageing
It is required that generally not high.Therefore, in the application other embodiment, mobile terminal can travel through a scratch file at regular intervals
Folder, the upload attribute of wherein each envelope rough draft mail of detection, when being at least in the rough draft mail of state to be uploaded in the presence of an envelope, then
Turn-on data business service uploads the rough draft mail.By the way that above-mentioned real-time synchronization band can be avoided to a certain extent with upper type
The problems come.In addition, use above situation is schematical citing, however it is not limited to which this applies situation.
Step S2013：Mail addition order is sent to the mail server, by the grass in state to be uploaded
Original text mail synchronization is to the mail server.
Mobile terminal to mail server send mail addition order (APPEND orders) before, it is necessary to first with mail
Server sets up TCP connections, and information exchange is carried out on this basis.APPEND orders in IMAP protocol allow on terminal device
A mail is carried into specified mail server file, the present embodiment will be in mobile terminal by APPEND orders and be treated
The rough draft mail synchronization of upload state is into the scratch file folder of mail server.Above rough draft mail is included in APPEND orders
Attribute, date created/creation time, mail size, and specific mail data (may include mail matter topics, Mail Contents
Deng), mail server is received after the APPEND orders of mobile terminal transmission, by the above rough draft included in APPEND orders
E-mail messages are preserved into scratch file folder, and then mobile terminal preserves the rough draft mail for needing to download to local data base,
So as to further edited or other processing, be finally completed synchronization of the rough draft mail in different terminals.
Step S2014：The rough draft mail in state to be uploaded is set to non-upload state.
The present embodiment is set to non-upload state by synchronous rough draft mail is completed, in case step S2012 detects the above
Rough draft mail is still within state to be uploaded and triggers simultaneously operating, causes rough draft mail to repeat upload, causes unnecessary net
The waste of network resource.
, may be due to the reason such as theme is similar, by synchronized mistake in addition, E-mail address user is when screening rough draft mail
Rough draft mail falsely drop to need synchronous rough draft mail, cause the same envelope rough draft mail without any operation by repeatedly
Pass, take unnecessary Internet resources and memory space.To avoid the generation of case above, the embodiment of the present application two provides another
A kind of outer rough draft mail synchronization method based on IMAP protocol.It is the step S2013 that the embodiment of the present application two is provided referring to Fig. 6
Flow chart.As seen from Figure 6, step S2013 comprises the following steps：
Step S20131：Whether detect in mail tabulation comprising corresponding with the rough draft mail in state to be uploaded
Mail piece identifier.If do not had in the mail tabulation comprising uniquely corresponding with the rough draft mail in state to be uploaded
Mail piece identifier, then perform step S20732.
Mail server therefrom extracts the effective of rough draft mail after the APPEND orders of mobile terminal transmission are received
Information (attribute of rough draft mail, date created/creation time, mail size, and specific mail data etc.), and will be above-mentioned
The effective information correspondence of rough draft mail is stored in the scratch file of mail server folder.Meanwhile, mail server can be reception
The each corresponding mail piece identifier of envelope rough draft mail creation arrived, and corresponding mail piece identifier is returned into mobile terminal, so as to
Mobile terminal identification has been synchronized to the rough draft mail of mail server.Mail piece identifier in the present embodiment is No. UID of mail,
Each envelope mail is unique in No. UID 32 certificates typically for mail in unique mark mailing system, mail server
One mail piece identifier of correspondence, to distinguish other mails.Mobile terminal is receiving the mail piece identifiers of mail server return
After symbol, it is stored in mail tabulation, mail tabulation is used to store the corresponding e-mail messages of each envelope rough draft mail, here
E-mail messages can include the effective information of above-mentioned rough draft mail and the identification information (such as No. UID) of rough draft mail.
Further, whether comprising corresponding with the rough draft mail in state to be uploaded in detection mail tabulation
Mail piece identifier, to determine the synchronous recording of correspondence rough draft mail.
Step S20132：Mail addition order is sent to the mail server.
If do not have to include in mail tabulation with the unique corresponding mail piece identifier of the rough draft mail in state to be uploaded,
Mail server is transmitted through on then showing this rough draft mail before this not, now, mail addition is sent to mail server and orders
Order, the same envelope rough draft mail without any operation is not resulted in so and repeats to upload.
