hope you fine. I am working on my vps email configuration setting. I configured the the postfix which is working on the mail-to-mail server and now i want to make a configuration with server-to-client email configuration, I already installed dovecot-core, dovecot-imapd, and dovecot-pop3d on my vps and also i generated the SSL decertification which is fine and by default at the time purchasing the VPS, and i am using the nginx server.Whenever i want to send email from my mobile to my vps it shows me the error message that your ssl certificate needs to be installed correctly. Now i want to configure my SSL certificate which is freely available on the Hostinger platform on my VPS, but I don't know how to do it. I already take help of AI but it does not give me the proper solution. will you please tell me what should i do now? I bought my vps on hostinger platform and now i want to embed the free SSL on my website but i don't know how to do this? Furthermore tell me is the free ssl certificates are working fine are there are risks availabe with it ?
I installed all the dependencies and package installed libraries.
