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.
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
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.
Attempt SASL authentication.
Send the USER command.
Send the PASS command. Returns the number of messages in the mailbox.
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.
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.
Return the sever's connection banner
Return a reference to a hash of the capabilties 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.
Just like capa, but only uses a cache from the last time we asked the server, so as to avoid asking more than once.
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.
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 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
.
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.
Returns the highest MSGNUM
of all the messages accessed.
Returns a list of two elements. These are the number of undeleted elements and the size of the mbox in octets.
Returns a list of two elements. These are the number of new messages
and the total number of messages for USER
.
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.
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 the status of the remote POP3 server. This includes reseting the status of all messages to not be deleted.
Quit and close the connection to the remote POP3 server. Any messages marked as deleted will be deleted from the remote mailbox.
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.
