    // Do any additional setup after loading the view, typically from a nib.

    SKPSMTPMessage *mail = [[SKPSMTPMessage alloc] init];
    [mail setSubject:@"测试"];  // 设置邮件主题
    [mail setToEmail:@"xx@xx "]; // 目标邮箱
    [mail setFromEmail:@"[email protected]"]; // 发送者邮箱

    [mail setRequiresAuth:YES];
    [mail setLogin:@"[email protected]"]; // 发送者邮箱账号
    [mail setPass:@"xxxxxxxxx"]; // 发送者邮箱密码
    [mail setWantsSecure:YES];  // 需要加密
    [mail setDelegate:self];


    NSDictionary *plainPart = [NSDictionary dictionaryWithObjectsAndKeys:
