step S324: downloading mail; mail downloading links and request parameters of each downloading link are obtained in batches, HTTP data packet sending and return data receiving are executed by multithreading, and mail downloading is completed;
step S325: mail has no mark; and checking and modifying the unread state of the mail again aiming at the mail with unread original state in the mailbox, and if the mail is the mail with read state, the mail is not affected.
The IMAP protocol is totally called Internet Message Access Protocol, also called interactive mail access protocol, and the IMAP mail receiving flow can realize mail receiving of all mail clips; the collecting flow comprises the following steps:
step S331: configuring an IMAP server; the method comprises the steps of including IMAP server address, IMAP server encryption information, IMAP server communication port and other configuration information;
step S332: authorizing login; establishing TCP connection by using the IMAP server address information configured in the step S331, and sending mailbox account authentication and mailbox encryption password in a preset encryption mode to complete authorized login;
step S333: traversing the mail folder; traversing the mail clip LIST through an LIST instruction, and circularly inquiring and traversing the mail LIST through a Fetch instruction;
step S334: downloading mail; mail downloading is completed by obtaining mail contents in batches and writing the mail contents into a local storage by using multiple threads.
The POP3 protocol is collectively referred to as Post Office Protocol version3, and the POP3 receipt flow is primarily directed to mail collection in the inbox. The collecting flow comprises the following steps:
step S341: configuring a POP3 server; configuration information such as POP3 server address, POP3 server encryption information, POP3 server communication port and the like is included;

step S344: downloading mail; mail downloading is completed by obtaining mail contents in batches and writing the mail contents into a local storage by using multiple threads.
The Exchange receiving flow can also collect mails under the condition that the account password is not obtained, and can receive the mails through the NTLM Hash obtained by a special channel. The collecting flow comprises the following steps:
step S351: the NTLM Hash is collected; in actual case handling work, particularly in a domain control scene, the NTLM Hash value of the target object can be intercepted in a network sniffing mode, a flow monitoring mode and the like;
step S352: NTLM Hash parsing; through mailbox information, domain control Domain and 32-bit NTLM Hash character strings of the incoming target object, an autonomous developed NTLM Hash analysis program is used for completing analysis of data and disguising of local authorization information;
step S353: authorizing login; after NTLM Hash analysis in step S352, the local computer has performed authorization information masquerading. At the moment, simulating the login of the Exchange mailbox; to achieve the effect of bypassing the server authentication authorization;
step S354: traversing the mail; traversing the mail clip list by using Exchange receiving protocol to complete ID list statistics and mail content inquiry of all mails;
step S355: downloading mail; mail downloading is completed by obtaining mail contents in batches and writing the mail contents into a local storage by using multiple threads.
The receiving monitoring flow is responsible for resource occupation monitoring of the whole receiving task, server limiting measure monitoring, receiving progress monitoring and the like.
The method specifically comprises the following steps:
step S1: creating a collection task; setting parameters such as mailbox receiving type, total receiving or appointed mailbox receiving quantity, total receiving or appointed sending time, single receiving or polling receiving and the like to initialize receiving tasks according to actual receiving requirements;
step S2: distributing the receiving lines; according to the actual active address of the target object, the country and the region where the target object is located are designated, the receiving program automatically selects the optimal line according to the information of the country and the region, the network line and the common line of the actual target object are kept in the similar region, and meanwhile, the network speed and the data downloading speed are considered;
step S3: starting multi-thread collection; in the mailbox receiving process, initializing a multithreading receiving method through the mailbox type of a target object, and carrying out data interaction and data downloading in a high concurrency mode;
step S4: monitoring a receiving strategy; and starting the monitoring of the receiving strategy in the mail downloading process. The mail receiving strategy monitoring has two main works, one is to monitor mail receiving statistics, flow limiting strategies and quantity limiting strategies of the mailbox, the other is to monitor mail receiving progress, and the mail receiving progress is fed back to a front-end user in a message queue mode;
step S5: completing a collection task; releasing the resources occupied by the mail receiving task, archiving and storing the downloaded mail, and displaying the log information and the statistical information in the mail receiving process.
The mail receiving method based on the multiple protocols can intelligently select the IP line according to the target mailbox and the region where the target object is frequently logged in the execution process, thereby improving the safety and preventing the server from abnormal reminding. And the method comprises the steps of Cookie collection, webMail collection, IMAP collection, POP3 collection and Exchange collection, and can flexibly adopt different collection modes in face of different scenes and requirements. The mail receiving method based on the multi-protocol adopts a distributed receiving mechanism, can realize high concurrency and multiple lines Cheng Shouxin in a short period, and meets the receiving requirement of mass mails. The mail receiving method based on the multiple protocols aims at different mailbox types and has a server flow monitoring strategy. And (3) limiting the daily flow of the mail downloading of part of mailboxes, limiting the maximum mail downloading quantity of part of mailboxes per hour, and the like, and automatically carrying out flow statistics and speed adjustment.
