=head1 NAME

Mail::SendEasy::SMTP - Handles the communication with the SMTP server without dependencies.

=head1 DESCRIPTION

This module will handle the communication with the SMTP server.
It hasn't dependencies and supports authentication.

=head1 USAGE

  use Mail::SendEasy ;

  $smtp = Mail::SendEasy::SMTP->new( 'domain.foo' , 25 , 120 ) ;
  
  if ( !$smtp->auth ) { warn($smtp->last_response_line) ;}
  
  if ( $smtp->MAIL("FROM:<$mail{from}>") !~ /^2/ ) { warn($smtp->last_response_line) ;}
  
  if ( $smtp->RCPT("TO:<$to>") !~ /^2/ ) { warn($smtp->last_response_line) ;}
   
  if ( $smtp->RCPT("TO:<$to>") !~ /^2/ ) { warn($smtp->last_response_line) ;}
    
  if ( $smtp->DATA =~ /^3/ ) {
    $smtp->print("To: foo@foo") ;
    $smtp->print("Subject: test") ;
    $smtp->print("\n") ;
    $smtp->print("This is a sample MSG!") ;
    if ( $smtp->DATAEND !~ /^2/ ) { warn($smtp->last_response_line) ;}
  }

  $smtp->close ;
