邮件发送程序遇到的问题
我通过SMTP写了个邮件发送程序，但是我却在dafu10000@yahoo.com.cn中收不到，不知道是代码的问题还是我操作系统问题（操作系统xp，我看服务中没有SMTP服务，是不是要装IIS才有，我登陆dafu10@126.com邮箱是可以发送邮件的,dafu10000@yahoo.com.cn也可以收到)，请高手指点。
代码如下：
#define _WIN32_WINNT 0x0400
#include <io.h>
#include <stdio.h>
#include <stdlib.h>
#include <windows.h>
#include <Tlhelp32.h>
#include <psapi.h>
#pragma comment(lib, "psapi.lib")
#pragma comment(lib, "user32.lib")
#pragma comment(lib, "ws2_32.lib")
char MailData[255] = "From: \"dafu10\" <dafu10@126.com>\r\n ";
//发送邮箱为dafu10@126.com,用户名、密码均为dafu10；接受邮箱为dafu10000@yahoo.com.cn。
void SendMail(void)
{
WSADATA wsaData;
WORD wVersionRequested = MAKEWORD(2, 2);
struct hostent *pHostent = NULL;
SOCKET server = INVALID_SOCKET;
struct sockaddr_in service;
char Buffer[1024] = {0};
WSAStartup(wVersionRequested, &wsaData);
server = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
pHostent = gethostbyname("smtp.126.com");
service.sin_family = AF_INET;
memcpy(&service.sin_addr.s_addr, pHostent->h_addr_list[0], pHostent->h_length);
service.sin_port = htons(25);
connect(server, (struct sockaddr*)&service, sizeof(service));
recv(server, Buffer, sizeof(Buffer), 0);
send(server, "HELO Server....\r\n", strlen("HELO Server....\r\n"), 0);
recv(server, Buffer, sizeof(Buffer), 0);
send(server, "AUTH LOGIN\r\n", strlen("AUTH LOGIN\r\n"), 0);
recv(server, Buffer, sizeof(Buffer), 0);
send(server, "bGJleW9uZDRrb21h\r\n", strlen("ZGFmdRkY\r\n"), 0);
recv(server, Buffer, sizeof(Buffer), 0);
send(server, "bGJleW9uZDRrb21h\r\n", strlen("ZGFmdRkY\r\n"), 0);
recv(server, Buffer, sizeof(Buffer), 0);
send(server, "MAIL FROM: <dafu10@126.com>\r\n", strlen("MAIL FROM: <dafu10@126.com>\r\n"), 0);
recv(server, Buffer, sizeof(Buffer), 0);
send(server, "RCPT TO: <dafu10000@yahoo.com.cn>\r\n", strlen("RCPT TO: <dafu10000@yahoo.com.cn\r\n"), 0);
recv(server, Buffer, sizeof(Buffer), 0);
send(server, "Data\r\n", strlen("Data\r\n"), 0);
recv(server, Buffer, sizeof(Buffer), 0);
send(server, MailData, strlen(MailData), 0);
recv(server, Buffer, sizeof(Buffer), 0);
send(server, "QUIT\r\n", strlen("QUIT\r\n"), 0);
WSACleanup();
printf("Success!");
ExitProcess(0);
return;
}
int main(void)
{
SendMail();
}
[解决办法]
XP的SMTP服务好像是需要额外装的。
你点控制面板，然后添加/删除程序，然后点左侧的组件管理，在那里面看一下吧...
