Retrieve e-mails using the POP3 protocol (RFC1939).
Errors triggered by invalid or negative replies from the POP3 server are signalled by raising a compound condition of the kinds exn and pop3.[procedure] (pop3:connect HOSTNAME USERNAME PASSWORD [VERBOSE [PORT]])
Connects to the server HOSTNAME using the POP3 protocol and identifies this client with USERNAME and PASSWORD. If the optional argument VERBOSE is given and not #f, then a protocol of the communication with the server is written to the value of (current-error-port). PORT specifies the port-number and defaults to 110.
This procedure returns an object representing the POP3 session.[procedure] (pop3:disconnect POP3)
Closes the connection identified by the session object POP3.[procedure] (pop3:pop3? X)
Returns #t if X is an POP3 session object, or #f otherwise.[procedure] (pop3:list POP3)
Returns the list of all available messages as an a-list, where each element in the list is a pair of the form (MESSAGE-ID . SIZE) representing the message-identifier and the size of the message in bytes.[procedure] (pop3:open POP3 INDEX [DELETE])
Returns a port for the message with id INDEX and returns an input-port that can be used to retrieve the header and the contents of the message. If the optional argument DELETE is given and not #f, then the message will be deleted on the server, when the port is closed.
It is not possible to call pop3:open before the port returned by a previously invoked call has been closed.
; Download and print all messages: (define p (pop3:connect "pop3.your-isp.net" "myname" "secret")) (for-each (match-lambda [(id . bytes) (print "Retrieving message " id ", " bytes " bytes:") (let ([port (pop3:open p id)]) (display (read-string #f port)) (close-input-port port) ) ] ) (pop3:list p) ) (pop3:disconnect p)
- 1.3 ported to CHICKEN 4
- 1.2 Replaced use of (end-of-file) with #!eof
- 1.1 Fixed bug that caused an unbound variable error if connection failed.
