ANPOP is a high-performance and easy-to-use POP3 component (mail component). It enables ASP/VB/VC++/C#/VB.NET/ASP.NET/Delphi or other COM environment applications to retrieve e-mail from a mail server based on POP3 protocol, and parse e-mail based on MIME. ANPOP supports all operations of POP3 protocol and provides many advanced features as follows: supports POP3 commands: USER, PASS, APOP, NOOP, RSET, TOP, LIST, STAT, UIDL, RETR, and QUIT; supports synchronous and asynchronous mode; gets e-mail headers without downloading the whole e-mail from a server; gets e-mail size/message ID from a server; deletes/undeletes e-mail; logs files to record all sessions between client and server; and loads e-mail from file or binary streams.
