NAME

       Mail::SpamAssassin::Client - Client for spamd Protocol

SYNOPSIS

         my $client = Mail::SpamAssassin::Client->new({
                                       port => 783,
                                       host => 'localhost',
                                       username => 'someuser'});
         or

         my $client = Mail::SpamAssassin::Client->new({
                                       socketpath => '/path/to/socket',
                                       username => 'someuser'});

         Optionally takes timeout, which is applied to IO::Socket for the
         initial connection.  If not supplied, it defaults to 30 seconds.

         if ($client->ping()) {
           print "Ping is ok\n";
         }

         my $result = $client->process($testmsg);

         if ($result->{isspam} eq 'True') {
           do something with spam message here
         }

DESCRIPTION

       Mail::SpamAssassin::Client is a module which provides a perl implementation of the spamd
       protocol.

PUBLIC METHODS

   new
       public class (Mail::SpamAssassin::Client) new (\% $args)

       Description: This method creates a new Mail::SpamAssassin::Client object.

   process
       public instance (\%) process (String $msg)

       Description: This method calls the spamd server with the PROCESS command.

       The return value is a hash reference containing several pieces of information, if
       available:

       content_length

       isspam

       score

       threshold

       message

   check
       public instance (\%) check (String $msg)

       Description: The method implements the check call.

       See the process method for the return value.

   headers
       public instance (\%) headers (String $msg)

       Description: This method implements the headers call.

       See the process method for the return value.

   learn
       public instance (Boolean) learn (String $msg, Integer $learntype)

       Description: This method implements the learn call.  $learntype should be an integer, 0
       for spam, 1 for ham and 2 for forget.  The return value is a boolean indicating if the
       message was learned or not.

       An undef return value indicates that there was an error and you should check the
       resp_code/resp_msg values to determine what the error was.

   report
       public instance (Boolean) report (String $msg)

       Description: This method provides the report interface to spamd.

   revoke
       public instance (Boolean) revoke (String $msg)

       Description: This method provides the revoke interface to spamd.

   ping
       public instance (Boolean) ping ()

       Description: This method performs a server ping and returns 0 or 1 depending on if the
       server responded correctly.

PRIVATE METHODS

   _create_connection
       private instance (IO::Socket) _create_connection ()

       Description: This method sets up a proper IO::Socket connection based on the arguments
       used when creating the client object.

       On failure, it sets an internal error code and returns undef.

   _parse_response_line
       private instance (@) _parse_response_line (String $line)

       Description: This method parses the initial response line/header from the server and
       returns its parts.

       We have this as a separate method in case we ever decide to get fancy with the response
