Embodiment
For making the purpose, technical solutions and advantages of the present invention express clearlyer, the present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
Fig. 3 is the structure chart of mail server system in the embodiment of the invention.As shown in Figure 3, mail server system comprises in the embodiment of the invention: mail distribution server (NameServer), a plurality of MTA server and a plurality of MDA server.
Described MTA server, be used to receive the mail of required transmission, and send the query requests of the address of the addressee that comprises this mail to described mail distribution server according to received mail, and receive the MDA server address that described mail distribution server returns, give this MDA server according to described MDA server address with described mail distribution then;
Described MDA server, be used for received mail delivery to this corresponding mailbox in mail recipient address; Regularly report the condition information of self to described mail distribution server by proxy modules (NameAgent);
Described NameServer is used for the condition information according to each MDA server of receiving, new configuration file more, the address of unified configuration MDA server; According to the address of the addressee in the query requests that receives, from configuration file, select and the corresponding MDA server address of described address of the addressee, selected MDA server address is returned to the MTA server that sends described query requests.
Above-mentioned MTA server can be Webmail, Pop3, Esmtp or Mx.And above-mentioned MDA server can be SmtpBG, and SmtpBG can be divided into foreign lands mail delivery acting server (EBG) and this territory mail delivery acting server (LocalBG) two big classes again.Wherein, EBG is responsible for handling the mail that deliver to foreign lands in this territory, and LocalBG is responsible for handling the mail that deliver to this territory to this territory or this territory foreign lands.In addition, an interface module (NameClientAPI) can be set also in above-mentioned NameServer, be used to handle received query requests and the information that reports.
In above-mentioned mail server system, described NameServer can select the mail delivery acting server of a MDA server as this mail according to the mail of required transmission from a plurality of MDA servers.Before this, NameServer can divide all MDA servers according to the condition information of each MDA server in the configuration file.Specifically, NameServer can carry out subregion according to its residing network area with all MDA servers, and the MDA server that is in the same network area belongs to same subregion, and described network area comprises telecommunications, Netcom or education network etc.; Can the MDA server in the same subregion be divided into a plurality of groups according to rule of classification then.Described rule of classification can set in advance according to actual conditions, and for example, rule of classification can be to divide into groups according to the IP address, also can be to divide into groups according to the type of server etc.
After carrying out above-mentioned division, above-mentioned mail server system can be the mail of required transmission and selects the MDA server of a MDA server as this mail, and with the mail distribution of required transmission on mutually should the MDA server.The method of concrete mail distribution is as described below.
Fig. 4 is the flow chart of the method for mail distribution in the embodiment of the invention.As shown in Figure 4, the method that mail server system carries out mail distribution in the embodiment of the invention comprises step as described below:
Specifically, the MTA server can send query requests to NameServer according to the mail of required transmission, comprises addressee's the information such as address of the mail of required transmission in this request.
Specifically, NameServer can be according to the information such as address of the addressee in the query requests, from configuration file, select and the corresponding MDA server address of described address of the addressee, and described MDA server address is returned to the MTA server that sends described query requests.
The described selection from configuration file comprises step as described below with the corresponding MDA server address of described address of the addressee:
A), from a plurality of subregions, select a subregion according to query requests.
Specifically, can from a plurality of MDA server partition, select a subregion according to the address of the addressee of the mail of required transmission in the query requests.
B), from selected subregion, select a grouping.
Specifically, can select a grouping in a plurality of groupings from selected subregion according to the address of the addressee of the mail of required transmission.
C), from selected grouping, select a MDA server.
Specifically, in all MDA servers from selected grouping, select a MDA server according to the state parameter that each MDA server in this grouping of being stored in the configuration file reports by NameAgent, the described state parameter that reports comprises: the load (Load) of the process number of queue length, mail server (for example, the number of smtpd process), server etc.That is to say that NameServer can go up the report state parameter according to above-mentioned, and uses predefined algorithm (for example, load-balancing algorithm or dynamical feedback equalization algorithm etc.), selects to be used for the MDA server of delivering mail according to qualifications.
Specifically, the MTA server is according to received MDA server address, with described mail distribution to the corresponding MDA server of received MDA server address on.
In addition, in the practical application scene, some abnormal conditions may appear.Below will introduce the method for above-mentioned mail server system to the processing of various abnormal conditions:
1) when abnormal conditions be: NameServer breaks down, and the MTA server can't be inquired about the address of MDA server to NameServer.
Processing method is: two NameServer are set and on each MTA the storage acquiescence delivering mail server list (ServerList), a configuration file is all arranged on every NameServe.When the MTA server need be inquired about the address of MDA server, can be at random send query requests to NameServe wherein.If this NameServe does not return the address of MDA server or returns error message, then the MTA server can send query requests to another NameServe.If two NameServer break down, then MTA returns the address of MDA server to the MTA server according to the ServerList of the acquiescence of self storing.
2) when abnormal conditions be: comprise a domain name in the query requests that NameServe received, and this domain name does not have corresponding MDA server in the configuration file of NameServe.
Solution: the acquiescence delivery server of in the configuration file of NameServer, specifying one group of overall situation in advance.When in the configuration file of NameServe during not with the corresponding MDA server of certain domain name, NameServer returns the address of the acquiescence delivery server of the described overall situation to the MTA server.
3) when abnormal conditions be: all the MDA servers in certain grouping all break down.
Solution: in the configuration file of NameServer, can be each MDA server grouping and specify the MDA server group of another group MDA server as acquiescence, when all the MDA servers in certain MDA server grouping of certain group domain name correspondence all go wrong, system will return the MDA server group of above-mentioned acquiescence to the MTA server.
4) when abnormal conditions be: self breaks down NameAgent, but the still normally operation of the MDA server at NameAgent place.
Solution: in general, because NameAgent's is relatively simple for structure, the possibility that breaks down is very little, therefore, when NameAgent breaks down, can think that fault has appearred in the MDA server at this NameAgent place, MDA server or other monitoring program are come fault is handled by system to system alarm.
5) when abnormal conditions be: NameAgent and MDA server be operate as normal all, but the MDA server has overstock a large amount of mails in formation.
Solution: because the state information about the MDA server that reports by NameAgent comprises: queue length, smtpd process number and Load, and NameServer can determine the quality of MDA server state according to the described state information that reports and certain algorithm (for example, load-balancing algorithm or dynamical feedback equalization algorithm etc.).After NameServer determined the state of MDA server, the address of MDA server that can state is good preferentially returned to corresponding M TA server.
In the configuration file of NameServer, the corresponding relation between domain name and the MDA server has been described.Owing between domain name and the MDA server too many data item is arranged,, the situation of domain name and MDA server can be documented on the independent configuration file for the convenience of updating maintenance.For example, domain name configuration file (USADomain.list) has form as described below:
*hotmail.com
*yahoo.*
…
MDA server profile (USAServer.list) has form as described below:
172.16.62.40:25
172.16.25.15:25
…
And the spendable configuration file of NameServer has form as described below:
[Default]
BGServerFile＝TELServer.list
[Group1]
DomainFile＝CNCDomain.list
BGServerFile＝CNCServer.list
BackupGroup＝Default
[Group2]
DomainFile＝EDUDomain.list
BGServerFile＝EDUServer.list
B?ackupGroup＝Group1
[SpecGroup1]
BGServerFile＝SPAMServer.list
BackupGroup＝Default
[SpecGroup2]
BGServerFile＝APIServer.list
BackupGroup＝SpecGroup2
NameServer.conf
Wherein, [Default] configuration section is used to indicate the acquiescence delivery server tabulation of the overall situation, not record in the configuration file of domain name at NameServer of the address of the addressee of certain mail, then can use the acquiescence delivery server of the overall situation in [Default] configuration section to tabulate (for example, TELServer.list).
[GroupX] configuration section (wherein, X=1,2 ...) correspond respectively to X grouping (Group), be used for describing the domain name of each grouping and the corresponding relation of MDA server.Wherein, DomainFile the tabulation of domain name described filename (for example, CNCDomain.list); The filename that BGServerFile describes a MDA server list (for example, CNCServer.list); BackupGroup then is used for when the server of all tabulations of [GroupX] configuration section all breaks down, the server that system default uses.BackupGroup can be used for specifying a standby grouping, and (for example, Group1), when all the MDA servers in this grouping all break down, system will use the server in the indicated grouping of BackGroup; And if do not have BackupGroup in this configuration section, then system default uses the server list of Default configuration section the inside.
[SpecGroupX] configuration section (wherein, X=1,2 ...) be used for specifying the group (i.e. X particular group) of a special purpose, can directly specify the MDA server in the group of using this special purpose to carry out the distribution of mail by to the calling of the interface module of NameServer.
In addition, in the communication architecture that NameServer adopted, NameServer can adopt a plurality of transmission control protocols (TCP) process to connect the server that each need be inquired about; And the vlan query protocol VLAN that NameServer adopted uses text formatting, and provides following order: QUERY, UPDATE, LIST, QUIT etc.Each server in the system can conduct interviews to NameServer by above-mentioned order.Below will be introduced above-mentioned these orders.
1) QUERY order
The QUERY order can be used for to the specific pairing MDA server address of addressee of NameServer inquiry.At this moment, NameServer can divide into groups to the addressee according to configuration information, and for each divides the address of the candidate MDA server of group selection some.For example:
QUERY<rcpt_count><spec_group_id>
<rcpt1>
<rcpt2>
<rcpt3>
+OK<group_count>
rcpt1＝serverA，serverB
rcpt2，rcpt3＝serverC
Wherein, QUERY is the multirow order, and first line command comprises command keyword and two parameters, and parameter rcpt_count is used to specify addressee's quantity of this inquiry, and parameter s pec_group_id is used for forcing to specify a certain group of MDA server; Since second line command is addressee information, addressee information of each order line input.
NameServer returns the multirow response with "+OK " beginning after according to above-mentioned QUERY order configuration file being inquired about.Wherein, group_count is used to indicate the number of the grouping that the addressee is divided into; Since second row, NameServer returns the situation of each grouping, each responsive trip returns the situation of a grouping, use CSV between the interior different addressee of same grouping, also use CSV between the interior different MDA server info of same grouping, separate with equal sign between addressee information and the MDA server info.For example, in the above-described embodiment, addressee rcpt1 is a grouping, and spendable MDA server is serverA and serverB; And addressee rcpt2 and rcpt3 are another grouping, and spendable MDA server is serverC.Wherein, the form of addressee information can be complete email address, for example, and [email protected]; The MDA server address can use the IP address: the form of port (ip:port), for example, 172.16.62.40:25.
Especially, when a certain receiver divides into groups corresponding a plurality of MDA server, NameServer can attempt described a plurality of MDA servers in order by NameClientAPI, thereby make NameServer to decide the Query Result that is returned according to certain strategy, for example, NameServer can use wheel to change (Round-Robin) algorithm the MDA server of a plurality of operational excellences is dispatched, and returns Query Result according to scheduling result.
2) UPDATE order
NameAgent on each MDA server can upgrade the state information of MDA server by UPDATE command request NameServer.For example:
UPDATE<svr_id><mail_queue><load><proc_num>
+OK<svr_id>is?on
-ERR?No?such?server.
Wherein, UPDATE order has four parameter: parameter s rv_id to represent the MDA server of certain appointment, can use the form of ip:port; Parameter m ail_queue represents queue length; Parameter l oad represents server load; Parameter p roc_num represents the smtpd number of processes.
If the state information of above-mentioned specified server has stored in the configuration file of NameServer, then NameServer returns the response with "+OK " beginning, wherein, " is on " expression NameServer has received the state information of the MDA server transmission of this use UPDATE order.
If above-mentioned specified server is not in the configuration file of NameServer, then NameServer returns the response with " ERR " beginning.
The NameAgent of MDA server needs regularly to use the UPDATE order to return the condition information of its MDA server of monitoring to NameServer.If NameServer does not receive the UPDATE order that the NameAgent of certain MDA server sends in certain time limit, think that then this MDA server breaks down, therefore, NameServer will no longer put into the Query Result that returns by NameClientAPI with the information of this MDA server.
3) LIST order
The state status that the LIST instruction is used for checking all MDA servers.Can not use this order generally speaking, this order is mainly used in debugging (debug).
4) QUIT order
The QUIT order is used for being connected with the NameServer disconnection.
By using the above-mentioned mail server system and the method for mail distribution, can be effectively from a plurality of MDA servers, select corresponding, state preferably the MDA server carry out the distribution of mail, make that all mail delivery acting servers can both obtain balanced the utilization in the mail server system, thereby improve the efficient of whole mail server system, and can handle various abnormal conditions effectively, even make under unusual situation, also can efficiently must utilize mail delivery acting server distribution mail.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
