Pop3客户端接收信件的整个流程： 1。连接到pop3服务器（默认端口110） 2。发送用户名（user） 3。发送密码（pass） 4。查询当前邮箱状态（stat） 5。查询服务器上所有邮件UID列表（UIDL） 6。查询本地所有邮件的UID列表，从而罗列出新邮件列表（本地UID列表是POP3客户端记录在日志文件中的） 7。对所有新邮件查询其大小（LIST） 8。下载所有新邮件（RETR）利用List提供的邮件大小信息 9。如果有必要，对所有新邮件标志为删除（DELE） 10。结束对话（QUIT） 11。解析本地下载邮件。(Pop3 client receives the entire flow of letters: 1. Connect to the pop3 server (default port 110) 2. Send user name (user) 3. Send password (pass) 4. Query current mail status (stat) 5. Query server UID list of all messages (UIDL) 6. Query local UID list of all messages, which set out the new mailing list (local UID is a POP3 client list recorded in the log file) 7. For all new e-mail inquiries about their size (LIST) 8. Download all new messages (RETR) to use List of information provided by message size 9. If necessary, for all new signs for the delete message (DELE) 10. The end of the dialogue (QUIT) 11.
