最近在用dede做站,看到后台有启用smtp方式发送邮件的设置,但没有验证。请问各位PHP大神,如何验证填写的smtp信息是否正确,验证包括端口、用户名、密码?求php代码实现,并输出这些错误信息,100分奉上!感谢。
dede的启用smtp方式发送邮件的设置,你是安装的插件吗?
我本地装的最新dede好像没这个功能设置哦
回楼上大牛,我只要能验证smtp信息是否正确就行,不需要做成dede插件。
//打开smtp服务器端口
$fp = @fsockopen($smtp_host, 25);
if (!$fp)
echo "Error: Cannot conect to ".$smtp_host."
";
$smtp = array( //1、EHLO,期待返回220或者250 array("EHLO ".$loc_host.$lb,"220,250","HELO error: "), //2、发送Auth Login,期待返回334 array("AUTH LOGIN".$lb,"334","AUTH error:"), //3、发送经过Base64编码的用户名,期待返回334 array(base64_encode($smtp_acc).$lb,"334","AUTHENTIFICATION error : "), //4、发送经过Base64编码的密码,期待返回235 array(base64_encode($smtp_pass).$lb,"235","AUTHENTIFICATION error : ") ); //5、发送Mail From,期待返回250 $smtp[] = array("MAIL FROM: <".$from.">".$lb,"250","MAIL FROM error: "); //6、发送Rcpt To。期待返回250 $smtp[] = array("RCPT TO: <".$to.">".$lb,"250","RCPT TO error: "); //7、发送DATA,期待返回354 $smtp[] = array("DATA".$lb,"354","DATA error: "); //8.0、发送From $smtp[] = array("From: ".$from.$lb,"",""); //8.2、发送To $smtp[] = array("To: ".$to.$lb,"",""); //8.1、发送标题 $smtp[] = array("Subject: ".$subject.$lb,"","");$result_str=""; //发送smtp数组中的命令/数据 foreach($smtp as $req) { //发送信息 @fputs($fp, $req[0]); //如果需要接收服务器返回信息,则 if($req[1]) { //接收信息 while($result = @fgets($fp, 1024)) { if(substr($result,3,1) == " ") { break; } }; if (!strstr($req[1],substr($result,0,3))) { $result_str.=$req[2].$result."<br>"; } } } //关闭连接 @fclose($fp); return $result_str; }
倒没有没弄过验证smtp的端口、用户名、密码,端口还好说,但用户名、密码的话,只能尝试去请求来判断了...
function smtp_sockopen_relay()
{
$this->log_write("Trying to ".$this->relay_host.":".$this->smtp_port."\n");
$this->sock = @fsockopen($this->relay_host, $this->smtp_port, $errno, $errstr, $this->time_out);
if (!($this->sock && $this->smtp_ok()))
{
$this->log_write("Error: Cannot connenct to relay host ".$this->relay_host."\n");
$this->log_write("Error: ".$errstr." (".$errno.")\n");
return FALSE;
}
$this->log_write("Connected to relay host ".$this->relay_host."\n");
return TRUE;;
