Connecting To External Smtp Server

[kotha]

Hi Admin,

 

Last few days I had an working php script which allowed me to send email using PHP PEAR by connecting to an external SMTP server (smtp.yandex.com).

 

However, since last 2 days probably I can see that the php script is unable to connect to the smtp server and thus not being able to send emails.

 

I have tested with following script to find out that somehow, heliohost is probably blocking the access to the smtp server / port. Since, I found this script being able to connect from a different php host. Can you please check and let me know what went wrong recently that I'm unable to connect to smtp server in question.

Test Script:

<?php
$timeout = 30; // your own timeout value
$connection_type = 'ssl'; // may be ssl, sslv2, sslv3 or tls
$host = 'smtp.yandex.com';
$port = 465;

$fp = stream_socket_client("{$connection_type}://{$host}:{$port}", $errno, $errstr, $timeout);

if (!$fp) {
    echo "$errstr ($errno)";
} else {
    echo "Connection established";
}
?>

Looking forward for your help!

Does it work now?

Does it work now?

 

No, It's still not working... I'm getting a connection timeout message...

Connection timed out (110)

The script snippet given above is hosted at:

Your link says connection established now.

Your link says connection established now.

 

This is kind of strange... I have been re-trying a number of times since your last reply, but still getting same timeout message.

To rule out possibilities of cached results, I have even tried accessing from different browsers, including my mobile browser over a different internet connection (though this has nothing to do with my internet connection).

 

Attached is the screenshot:

Update:

I see it working now, and getting "Connection established" message.

 

Hope this problem solved completely... I will get back if the problem re-appears. Hope not...

Thanks!

Here's why http://bybyron.net/php/tools/dns_records.php?domain=smtp.yandex.com&rec=A I whitelisted the result of typing 'ping -c 1 smtp.yandex.com' but since there are five A records that means your script will work about 20% of the time. Now that all 5 IPs are whitelisted it should work 100% of the time.
