public void sendMessage(String addressTo,String mailText){
 try{
System.out.println(receive());
String hostName = InetAddress.getLocalHost().getHostName();
out.println("EHLO " + hostName);
String ehlo ;
do{
ehlo = receive();
System.out.println(ehlo);
}
while(!ehlo.equals("250 8BITMIME"));
out.println("AUTH LOGIN");
System.out.println(receive());
out.println(EncodeBase.enCode(new UserInfo().getUserName().getBytes()));
System.out.println(receive());
out.println(EncodeBase.enCode(new UserInfo().getUserPass().getBytes()));
System.out.println(receive());
out.println("Mail From:<" + new UserInfo().getUserAddress() + ">");
System.out.println(receive());
out.println("Rcpt To:<" + addressTo + ">");
System.out.println(receive());
out.println("Data");
System.out.println(receive());
out.println(mailText);
out.println(".");
System.out.println(receive());
out.println("Quit");
System.out.println(receive());

}catch(Exception e){
System.out.println("发送消息出错了");
}
