Abstract
The invention discloses a method and device for sending emails. The method comprises the steps of enabling an email sending server to obtain an email address of a recipient in the emails; enabling the email sending server to read a server domain name in the email address of the recipient; enabling the email sending server to determine an IP address of an email receiving server corresponding to the email address of the recipient according to the server domain name in the email address of the recipient; and enabling the email sending server to directly send the emails to the email receiving server corresponding to the IP address. According to the method and device for sending the emails, the problem that an SMTP relay server processes plenty of emails in the email sending process in the prior art, so that the email transmission speed is slow is solved, the email sending speed is improved, and email sending quality is further improved.
Description
Technical field
The application relates to internet arena, in particular to a kind of sending method and device of Email.
Background technology
Email is widely used by people as a kind of communication way.Common E-mail sending system sends the process of Email, need to specify the SMTP Relay Server of mail, to carry out relay-type transmission by SMTP Relay Server, so that network layer is directly during UNICOM between sender server and mail reception server, mail can transmit by SMTP Relay Server, the sending to of certified mail.
In above-mentioned e-mail sending formula, sender, when network layer between mail reception server can directly be communicated with, by SMTP Relay Server, being undertaken that mail transmits is no longer just an extraordinary way.Specifically, first, because SMTP Relay Server need to be processed a large amount of mails, tend to make mail stand-by period in queue very long, the speed that mail is transmitted is affected; Secondly, in current business activity, often need to send a large amount of commercial papers by mail tabulation, use SMTP Relay Server to send the quality that is difficult to guarantee transmission, likely occur the phenomenon that mail is lost.
For mail process of transmitting SMTP Relay Server in correlation technique, process a large amount of mails and cause the slow-footed problem of mail transmission, do not propose temporarily at present effective solution.
Summary of the invention
The application's main purpose is to provide a kind of sending method and device of Email, to solve mail process of transmitting SMTP Relay Server in correlation technique, processes a large amount of mails and causes the slow-footed problem of mail transmission.
According to the application aspect, a kind of sending method of Email is provided, the method comprises: outgoing mail server obtains the addresses of items of mail of addressee in Email; Outgoing mail server reads the server domain name in addressee's addresses of items of mail; Outgoing mail server is determined the IP address of this addressee's the corresponding mail reception server of addresses of items of mail according to the server domain name in addressee's addresses of items of mail; Outgoing mail server is directly sent to mail reception server corresponding to IP address by Email.
Further, outgoing mail server determines that according to the server domain name in addressee's addresses of items of mail the step of IP address of this addressee's the corresponding mail reception server of addresses of items of mail comprises: the canonical name of determining the server domain name in addressee's addresses of items of mail; According to canonical name, determine the IP address of addressee's the corresponding mail reception server of addresses of items of mail.
Further, determine that the step of the canonical name of the server domain name in addressee's addresses of items of mail comprises: on DNS, inquire about the whether existential specification title of server domain name in addressee's addresses of items of mail, if exist, obtain canonical name; Also whether the canonical name that judgement is obtained existential specification title; The also existential specification title of canonical name of obtaining if judge, continues to obtain canonical name, until not existential specification of the canonical name title of obtaining, the canonical name of the server domain name in the addresses of items of mail using the canonical name finally obtaining as addressee.
Further, according to canonical name, determine that the step of IP address of addressee's the corresponding mail reception server of addresses of items of mail comprises: mail exchange record corresponding to query specification title on DNS; According to mail exchange record, determine the IP address of addressee's the corresponding mail reception server of addresses of items of mail.
Further, the step of the IP address of the corresponding mail reception server of addressee's addresses of items of mail comprises: by mail exchange record according to prioritization; According to the journal of mail exchange record, determine the IP address of addressee's the corresponding mail reception server of addresses of items of mail.
According to the application on the other hand, provide a kind of dispensing device of Email, this device is positioned on outgoing mail server, comprising: acquiring unit, for obtaining Email addressee's addresses of items of mail; Reading unit, for reading the server domain name of addressee's addresses of items of mail; Determining unit, for determining the IP address of this addressee's the corresponding mail reception server of addresses of items of mail according to the server domain name of addressee's addresses of items of mail; Transmitting element, is directly sent to mail reception server corresponding to IP address for Email just.
Further, determining unit comprises: first determines subelement, for determining the canonical name of server domain name of addressee's addresses of items of mail; Second determines subelement, for determine the IP address of addressee's the corresponding mail reception server of addresses of items of mail according to canonical name.
Further, first determines that subelement comprises: the first acquisition module, for inquire about the whether existential specification title of server domain name of addressee's addresses of items of mail on DNS, if exist, obtains canonical name; Judge module, for judging whether the canonical name that the first acquisition module obtains goes back existential specification title; The second acquisition module, when judging the canonical name existential specification title that the first acquisition module obtains at judge module, continues to obtain canonical name, until not existential specification of the canonical name title of obtaining; And determination module, for the canonical name of the server domain name of the addresses of items of mail using the canonical name finally obtaining as addressee.
Further, second determines that subelement comprises: enquiry module, for mail exchange record corresponding to query specification title on DNS; Determination module, for determining the IP address of addressee's the corresponding mail reception server of addresses of items of mail according to mail exchange record.
Further, determination module comprises: sequence submodule, for by mail exchange record according to prioritization; Determine submodule, for determine the IP address of addressee's the corresponding mail reception server of addresses of items of mail according to the journal of mail exchange record.
By the application's technical scheme, according to the address resolution of addressee in Email, go out the IP address of mail reception server domain name, after determining the IP address of mail reception server domain name, directly Email is sent to mail reception server corresponding to this IP address, without using SMTP Relay Server to carry out refile.This e-mail sending formula has effectively solved mail process of transmitting SMTP Relay Server in correlation technique and has processed a large amount of mails and cause the slow-footed problem of mail transmission, promoted the speed that mail sends, further, SMTP Relay Server is processed the problem that mail that a large amount of mails may cause is lost, and has promoted mail and has sent quality.
