利用C++Builder中的NMSMTP发送电子邮件(能通过邮箱的验证)

摘要：最近通过程序发现：在头文件里加上

#include “idcoder3to4.hpp“

用Base64Encode()函数对用户名和密码编码

NMSMTP1->Host = "smtp.emailsos.net"; //SMTP主机名

NMSMTP1->UserID = "dgyanyong"; //用户名

NMSMTP1->PostMessageA->FromAddress = "dgyanyong@163.com"; //发信人地址

NMSMTP1->PostMessageA->ToAddress->Clear(); //收信人地址清空

NMSMTP1->PostMessageA->ToAddress->Text = "dgyanyong@sina.com"; //收信人地址

NMSMTP1->PostMessageA->ToCarbonCopy->Text = "dgyanyong@chinaren.com"; //抄送地址

NMSMTP1->PostMessageA->ToBlindCarbonCopy->Text = "dgyanyong@163.com"; //暗送地址

NMSMTP1->PostMessageA->Subject = "test message"; //邮件标题

NMSMTP1->PostMessageA->Body->Add("this is a test message!"); //邮件内容

NMSMTP1->PostMessageA->Attachments->Text = "C://qq.doc"; //邮件附件

NMSMTP1->PostMessageA->LocalProgram = "SendMail";

NMSMTP1->Connect();

if (CheckBox1->Checked == true)

{

AnsiString userName = Base64Encode("dgyanyong"); //将用户名编码

AnsiString password = Base64Encode("dgyanyong"); //将密码编码

NMSMTP1->Transaction("auth login"); //开始验证

NMSMTP1->Transaction(userName);

NMSMTP1->Transaction(password);

}

NMSMTP1->SendMail();

Memo1->Lines->Add("发送邮件成功");

NMSMTP1->Disconnect();

上述邮箱、163邮箱的用户名和密码均属虚构，只是做个范例，用户可以根据自己的需要设定。
