A pure-perl implementation of a POP3 client.

####
# raw interface
####
my $pop = Net::POP3.new(:server("your.server.here"), :port(110), :debug, :raw);
$pop.get-response # +OK

$pop.apop-login("username", "password");
# or (less secure)
$pop.user("username");
$pop.pass("password");

my $message-list = $pop.list; # +OK 2 messages\r\n1 120\r\n...
say $pop.retr(1); # +OK \r\nFrom:...
$pop.dele(1);
$pop.quit;

####
# simple interface
####
my $pop = Net::POP3.new(:server("your.server.here"), :port(110), :debug);
$pop.auth("username", "password"); # tries apop, then falls back to user/pass
my $count = $pop.message-count;
my @messages = $pop.get-messages;
for @messages {
    my $unique-id = .uid;
    my $raw-data = .data;
    my $email-mime = .mime; # returns Email::MIME object
                            # (requires Email::MIME installed to work)
    .delete;
}
$pop.quit;

Note that all of these methods should return a true value (or a valid false response, such as '0' from message-count) on success or a Failure object on failure.

• new(:$server!, :$port, :$debug, :$socket, :$ssl, :$starttls, :$plain)

  Creates a new POP3 client and opens a connection to the server.

  $port defaults to 110.

  $debug will print the network traffic to $*ERR if set.

  $socket allows you to use a class other than IO::Socket::INET for network communication. If you pass in a defined object, Net::POP3 will assume it is an already connected socket.

• auth($username, $password)

  Authenticates with the server. Attempts APOP first, and if the server doesn't support APOP or if the APOP login fails, will attempt a USER + PASS plain text login.

• message-count()

  Returns the number of messages in your mailbox.

• get-message(:$sid, :$uid)

  Returns a Net::POP3::Message object that refers to the message with the specified session id ($sid, the standard POP3 message number) or unique id ($uid, as returned from UIDL. NYI)

• get-messages()

  Returns a list of Net::POP3::Message objects, one for each message in the current mailstore.

• quit()

  Commits any message deletions and closes the connection to the server.

This class contains the actual message from the POP3 server.

• size()

  Returns the size of the message, in octets.

• uid()

  Returns the unique id of the message (as returned by UIDL)

• delete()

  Deletes this message from the POP3 server. Will not take effect until .quit is called on the main object.

• data()

  Returns the raw email message as a string.

• mime()

  Returns the email message as an Email::MIME object. Note that this will fail if Email::MIME is not installed.
