我一直在用PHP编写一个发送邮件的类,我决定使用Zend框架。此类使用用户的SMTP配置发送邮件。截至目前,我正在使用提供的用户凭据检查用户的SMTP配置,并向“虚拟”电子邮件地址发送“虚拟”电子邮件,并捕获可能出错的ZendException
类。这是一种可怕的方法,原因有很多:
以下是我正在做的测试SMTP配置是否有效的示例:
public function validSMTP () {
// Get the user's SMTP configuration
$config = $this->getConfiguration ();
// Create a new Zend transport SMTP object
$transport = new Zend_Mail_Transport_Smtp ( $config ["hostname"], [
"auth" => "login",
"ssl" => $config ["protocol"],
"port" => $config ["port"],
"username" => $config ["from"],
"password" => $config ["password"]
]);
// Create a new message and send it to dummy email
$mail = new Zend_Mail ("UTF-8");
$mail->setBodyText ( "null" );
$mail->setFrom ( $config ["from"] );
$mail->addTo ( "dev@null.com" );
$mail->setSubject ( "Test" );
// Attempt to send the email
try {
// Send the email out
$mail->send ( $transport );
// If all is well, return true
return true;
}
// Catch all Zend exceptions
catch ( Zend_Exception $exception ) {
// Invalid configuration
return false;
}
}
所以我的问题是:有更好的方法吗? Zend_Mail 有这样的内置功能吗?我看了一遍,在 Zend_Mail 中找不到任何内置内容。提前谢谢你的回答!

我在documentation中没有看到任何表明可以测试SMTP身份验证而无需实际尝试发送邮件的方法。也许当你调用setOptions
或setConnectionConfig
时,它会尝试登录并在失败时抛出异常,但我怀疑没有。
不是每次要发送邮件时执行验证检查,而是将配置数据和验证结果保存在文件中。然后在进行SMTP检查之前,请阅读该文件并检查配置设置是否相同。如果是,只需返回保存的结果。
这解决了问题列表中的前两项,如果配置无效,他们只会第一次收到退回邮件。

我决定手动检查,我会在下面发布最终结果,以便将来可以帮助某人。感谢@Barmar帮助我搜索文档并得出结果 Zend_Mail 框架不支持这样的功能。不幸的是,以下方法仅适用于SSL,因为TLS涉及在EHLO命令之后加密(以及更多)。如果配置有效,则返回 true ,否则返回字符串形式无效的原因。
public function validSMTP () {
// Initialize client configuration, for this example
$config = [
"hostname" => "smtp.gmail.com",
"port" => 465,
"protocol" => "ssl",
"username" => "USERNAME",
"password" => "PASSWORD",
];
// Add the connection url based on protocol
$config ["url"] = $config ["protocol"] . "://" . $config ["hostname"];
// Open a new socket connection to the SMTP mail server
if ( !( $socket = fsockopen ( $config ["url"], $config ["port"], $en, $es, 15 ) ) ) {
// Could not establish connection to host
return "Connection failed, check hostname/port?";
}
// Make sure that the protocol is correct
if ( $this->status_match($socket, '220') === false ) {
// Probably a wrong protocol (SSL/TLS)
return "Connection failed, check protocol?";
}
// Send hello message to server
fwrite ( $socket, "EHLO " . $config ["hostname"] ."\r\n" );
if ( $this->status_match ( $socket, "250" ) === false ) {
// If Hello fails, say config is invalid
return "Invalid SMTP configuration";
}
// Request to login
fwrite ( $socket, "AUTH LOGIN\r\n" );
if ( $this->status_match ( $socket, "334" ) === false ) {
return "Invalid SMTP configuration";
}
// Send the username
fwrite ( $socket, base64_encode ( $config [ "username" ] ) . "\r\n" );
if ( $this->status_match ( $socket, "334" ) === false ) {
// If failed, warn that invalid username password was passed
return "Invalid username/password combination.";
}
// Send the password
fwrite ( $socket, base64_encode ( $config [ "password" ] ) . "\r\n" );
if ( $this->status_match ( $socket, "235" ) === false ) {
// If failed, warn that invalid username password was passed
return "Invalid username/password combination.";
}
// Close the socket connections
fclose ( $socket );
// Return true, if everything above passed
return true;
}
private function status_match ( $socket, $expected ) {
// Initialize the response string
$response = '';
// Get response until nothing but code is visible
while ( substr ( $response, 3, 1) != ' ' ) {
// Receive 250 bytes
if ( !( $response = fgets ( $socket, 256 ) ) ) {
// Break if nothing else to read
break;
}
}
// If the status code is not what was expected
if ( !( substr ( $response, 0, 3 ) == $expected ) ) {
// Return false
return false;
}
// Otherwise return true
return true;
}
