Some Important Notes regarding SMTP

• Sometimes SSL encryption has some issues in some server as PHP is very strict now a days to check SSL. In that case, please choose TLS
• If you choose TLS, then dont forget to change the SMTP Port accordingly (in most cases, it is 587. But on your server it could be different)
• If you still face issues , then please contact hosting support & show them the SMTP details you are using in Admin Panel's SMTP form. It mostly depends on server so SMTP issue can only be solved by hosting support.
