英文:
GMAIL SMTP Connect Fails On Server But Works On Local
问题
I am using the Chilkat library to send email. It works perfectly on my local server/PC, but on the live server, it fails to connect to SMTP.
I've tried both SSL and TLS ports (465/587), but both fail with the same error message.
Here is the relevant part of the code to connect to Google SMTP server:
// init
$smtp = new CkMailMan();
$smtp->put_VerboseLogging(true);
$smtp->put_SmtpHost('smtp.gmail.com');
$smtp->put_SmtpPort(465);
$smtp->put_SmtpSsl(true);
// connect
if (!$smtp->SmtpConnect()) {
file_put_contents('./log/smtp_error_' . $GLOBALS['unixTime'] . '.log', $smtp->lastErrorXml());
unset($smtp);
echo '!failed!';
exit();
}
And here is the log file:
<ChilkatLog>
<SmtpConnect ms="30066">
<DllDate>Jun 25 2022</DllDate>
<ChilkatVersion>9.5.0.91</ChilkatVersion>
<!-- ... (log details) ... -->
<error>Failed.</error>
</SmtpConnect>
</ChilkatLog>
I've consulted with server tech, and they confirmed that all ports (465, 587, 25) are open. However, it's not working on the Linux server with Plex.

i have consulted with server tech and they said, all the port 465,587,25 all is open.
so, i am so confused why it is not working?
info: it's linux server with plex

无论你的服务器技术如何说，你都应该验证端口是否开放，并至少排除一个可能性。
以下是一个简单的脚本，尝试通过各种端口连接，并为每个端口返回成功或错误消息。
<?php
$servers = array(
array("ssl://www.google.com", 443),
array("smtp.gmail.com", 465),
array("smtp.gmail.com", 587),
);
foreach ($servers as $server) {
list($server, $port) = $server;
echo "<h1>尝试连接到 <tt>$server:$port</tt></h1>\n";
flush();
$socket = fsockopen($server, $port, $errno, $errstr, 10);
if(!$socket) {
echo "<p>错误：$server:$port - $errstr ($errno)</p>\n";
} else {
echo "<p>成功：$server:$port - 正常</p>\n";
}
flush();
}
?>

Regardless of what your server tech says, you should validate that the ports are open and eliminate at least one of the possibilities.
Here's a simple script that attempts to connect through various ports, and returns a SUCCESS or ERROR message for each.
<?php
$servers = array(
array("ssl://www.google.com", 443),
array("smtp.gmail.com", 465),
array("smtp.gmail.com", 587),
);
foreach ($servers as $server) {
list($server, $port) = $server;
echo "<h1>Attempting connect to <tt>$server:$port</tt></h1>\n";
flush();
$socket = fsockopen($server, $port, $errno, $errstr, 10);
if(!$socket) {
echo "<p>ERROR: $server:$portsmtp - $errstr ($errno)</p>\n";
} else {
echo "<p>SUCCESS: $server:$port - ok</p>\n";
}
flush();
}
