I'm using PHP 5.6 i think problem is in version of PHP let me know which package i should select for this version or i have to change version.

Hey @arsalahmed786

Check the error logs under Utilites > Logs > Actvity log, you can also get more infor on the SMTP Error by using these steps

Sometimes the error output in the Activity Log when sending of emails via SMTP fails can lack verbosity or the underlying cause may be different from the message that is ultimately displayed. Adding the following line to the configuration.php file will output a lot of debugging information when a mail is being sent manually, provided the Setup > General Settings > Mail tab > Mail Type is SMTP:

$smtp_debug = true;

After sending an email manually, the interaction between your server and the email server will be displayed on-screen for debugging purposes. Once finished, be sure to revert the change to the configuration.php file.

First of all thanks for the reply, i didn't added "$smtp_debug = true;" just change ports and it fine now Thanks, now i'm using port 443 for SSL

but thanks for your help, just want to know if it added "$smtp_debug = true;" on configuration.php file then it will debug the problem? or show the entire logs? just want to know if in case if i have face that problem again.
