Net::POP3(3pm)                        Perl Programmers Reference Guide                        Net::POP3(3pm)



NAME
       Net::POP3 - Post Office Protocol 3 Client class (RFC1939)

SYNOPSIS
           use Net::POP3;

           # Constructors
           $pop = Net::POP3->new('pop3host');
           $pop = Net::POP3->new('pop3host', Timeout => 60);

           if ($pop->login($username, $password) > 0) {
             my $msgnums = $pop->list; # hashref of msgnum => size
             foreach my $msgnum (keys %$msgnums) {
               my $msg = $pop->get($msgnum);
               print @$msg;
               $pop->delete($msgnum);
             }
           }

           $pop->quit;

DESCRIPTION
       This module implements a client interface to the POP3 protocol, enabling a perl5 application to talk
       to POP3 servers. This documentation assumes that you are familiar with the POP3 protocol described in
       RFC1939.

       A new Net::POP3 object must be created with the new method. Once this has been done, all POP3
       commands are accessed via method calls on the object.

CONSTRUCTOR
       new ( [ HOST ] [, OPTIONS ] 0
           This is the constructor for a new Net::POP3 object. "HOST" is the name of the remote host to
           which an POP3 connection is required.

           "HOST" is optional. If "HOST" is not given then it may instead be passed as the "Host" option
           described below. If neither is given then the "POP3_Hosts" specified in "Net::Config" will be
           used.

           "OPTIONS" are passed in a hash like fashion, using key and value pairs.  Possible options are:

           Host - POP3 host to connect to. It may be a single scalar, as defined for the "PeerAddr" option
           in IO::Socket::INET, or a reference to an array with hosts to try in turn. The "host" method will
           return the value which was used to connect to the host.

           ResvPort - If given then the socket for the "Net::POP3" object will be bound to the local port
           given using "bind" when the socket is created.

           Timeout - Maximum time, in seconds, to wait for a response from the POP3 server (default: 120)

           Debug - Enable debugging information

METHODS
       Unless otherwise stated all methods return either a true or false value, with true meaning that the
       operation was a success. When a method states that it returns a value, failure will be returned as
       undef or an empty list.

       auth ( USERNAME, PASSWORD )
           Attempt SASL authentication.

       user ( USER )
           Send the USER command.

       pass ( PASS )
           Send the PASS command. Returns the number of messages in the mailbox.

       login ( [ USER [, PASS ]] )
           Send both the USER and PASS commands. If "PASS" is not given the "Net::POP3" uses "Net::Netrc" to
           lookup the password using the host and username. If the username is not specified then the
           current user name will be used.

           Returns the number of messages in the mailbox. However if there are no messages on the server the
           string "0E0" will be returned. This is will give a true value in a boolean context, but zero in a
           numeric context.

           If there was an error authenticating the user then undef will be returned.

       apop ( [ USER [, PASS ]] )
           Authenticate with the server identifying as "USER" with password "PASS".  Similar to "login", but
           the password is not sent in clear text.

           To use this method you must have the Digest::MD5 or the MD5 module installed, otherwise this
           method will return undef.

       banner ()
           Return the sever's connection banner

       capa ()
           Return a reference to a hash of the capabilities of the server.  APOP is added as a pseudo
           capability.  Note that I've been unable to find a list of the standard capability values, and
           some appear to be multi-word and some are not.  We make an attempt at intelligently parsing them,
           but it may not be correct.

       capabilities ()
           Just like capa, but only uses a cache from the last time we asked the server, so as to avoid
           asking more than once.

       top ( MSGNUM [, NUMLINES ] )
           Get the header and the first "NUMLINES" of the body for the message "MSGNUM". Returns a reference
           to an array which contains the lines of text read from the server.

       list ( [ MSGNUM ] )
           If called with an argument the "list" returns the size of the message in octets.

           If called without arguments a reference to a hash is returned. The keys will be the "MSGNUM"'s of
           all undeleted messages and the values will be their size in octets.

       get ( MSGNUM [, FH ] )
           Get the message "MSGNUM" from the remote mailbox. If "FH" is not given then get returns a
           reference to an array which contains the lines of text read from the server. If "FH" is given
           then the lines returned from the server are printed to the filehandle "FH".

       getfh ( MSGNUM )
           As per get(), but returns a tied filehandle.  Reading from this filehandle returns the requested
           message.  The filehandle will return EOF at the end of the message and should not be reused.

       last ()
           Returns the highest "MSGNUM" of all the messages accessed.

       popstat ()
           Returns a list of two elements. These are the number of undeleted elements and the size of the
           mbox in octets.

       ping ( USER )
           Returns a list of two elements. These are the number of new messages and the total number of
           messages for "USER".

       uidl ( [ MSGNUM ] )
           Returns a unique identifier for "MSGNUM" if given. If "MSGNUM" is not given "uidl" returns a
           reference to a hash where the keys are the message numbers and the values are the unique
           identifiers.

       delete ( MSGNUM )
           Mark message "MSGNUM" to be deleted from the remote mailbox. All messages that are marked to be
           deleted will be removed from the remote mailbox when the server connection closed.

       reset ()
           Reset the status of the remote POP3 server. This includes resetting the status of all messages to
           not be deleted.

       quit ()
           Quit and close the connection to the remote POP3 server. Any messages marked as deleted will be
           deleted from the remote mailbox.

NOTES
       If a "Net::POP3" object goes out of scope before "quit" method is called then the "reset" method will
       called before the connection is closed. This means that any messages marked to be deleted will not
       be.
