pop3browser -- small perl script to access POP3 mail accounts DESCRIPTION
pop3browser is a perl script that uses libnet-perl to give access to POP3 mail accounts without fetching the messages. pop3browser can be used to delete unwanted mails (SPAM), especially when they come with large attachments, before downloading them over low-bandwidth connections. The --limit option of fetchmail is very useful to filter such large mails which can then be inspected with pop3browser. The program supports normal POP3 authentication and APOP. USAGE
pop3browser welcomes you with a short copyright note and a command line prompt. The settings for a mailbox (host, password etc.) have to be specified in a configuration file (similar to fetchmail). pop3browser understands the following commands: hosts list available hosts specified in .pop3browserrc login n log into host no. n, use 'hosts' to get a list of available hosts o(pen) n same as login apop n same as login but uses APOP c(lose) delete messages marked for deletion and close current connection list list sizes and message numbers of the mails on the account s(how) n show header and some body lines of mail number n m(ailbox) list message number, size, sender and subject for each mail d(elete) n delete mail number n undel(ete) n undelete mail number n k(ill) expr delete mails matching expr in header u(nkill) expr undelete mails matching expr in header q(uit) delete messages marked for deletion and quit program exit same as quit help print a command summary CONFIG FILE
The definitions for a mailbox are specified in ~/.pop3browserrc. One line per mailbox. Lines starting with # are ignored. Each definition must be in the following form:.br hostname <tab or space> userid <tab or space> password <tab or space> protocol (optional) For example: #definition for bar@pop.foo.com #pop-server UID passwd protocol pop.foo.com bar s3cr3t apop #end of definition Recognised options for the protocol are pop3 and apop. If no protocol is specified the command login/open assumes pop3. The command apop ignores the protocol option. To override the default header-filter of the show command you can specify a custom set of keywords in ~/.pop3browserrc. Lines starting with "@headpattern" or "@bodylines" are parsed by pop3browser. Settings for the header-filter must be in the following form: @headpattern <tab or space> = <tab or space> "<keyword1>","<keyword2>",.... The filter keywords are matched against the start of a header line. Settings for the number of body lines to show, have to be in the following form: @bodylines <tab or space> = <tab or space> <Number> Example: @headpatterns = "From:","To:","Subject:","Date:","CC" @bodylines = 10 The file ~/.pop3browserrc must only be readable for the owning user. pop3browser corrects other file modes automatically.

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. SEE ALSO
