Differences and connections between POP3, SMTP, and IMAPPOP3POP3 is the abbreviation for post Office Protocol 3, the 3rd version of the Post Office Protocol, which specifies how to connect personal computers to the Internet's mail servers and electronic protocols for downloading e-mail.

The SMTP server is the outgoing mail server that follows the SMTP protocol.SMTP authentication, in short, requires that the account name and password must be provided before the SMTP server can be logged in, which makes it possible for spammers to have no opportunity.The purpose of increasing SMTP authentication is t

are fed back to the server, the messages are manipulated, and the messages on the server do the corresponding actions.at the same time, IMAP , like POP3, provides a convenient e-mail download service that allows users to read offline. IMAP The Summary browsing feature allows you to decide whether or not to download after you have read all the message arrival time, subject, sender, size, etc. . In addition, IMAP is better able to support access to new messages from multiple different devices at

1, modify the user process can open the number of files limitOn a Linux platform, regardless of whether you write a client or a service-side program, the highest concurrency is limited by the number of files that can be opened by the system at the same time as the user's single process (because the system creates a socket handle for each TCP connection) for high concurrent TCP connection processing. Each socket handle is also a file handle. You can us
