Enable a CentOS 7 server send email via SSL

cn flag

I have a CentOS 7 server running lampp, with domain name xxx.example.com. I have successfully config the SSL certificate for https://xxx.example.com.

For email notification purpose, I need to send some emails. My smtp server's domain is smtp.example.com. I could send email in my local environment (Windows 10, xampp) with SSL activated. But when I deploy the site on CentOS, it can't send email with SSL option activated. I have to bypass the SSL verification part to send the email:

 'stream' => [
         'ssl' => [
                'allow_self_signed' => true,
                'verify_peer' => false,
                'verify_peer_name' => false,
          ],
  ],

So, how should I set up my CentOS environment to send email with SSL correctly?

What host name is your application connecting to? How have you verified that, besides your *https* service, you also configured your *smtp* service to use an appropriate host name & certificate?

My email program connects to `smtp.example.com`. I could successfully send the email with SSL in my local requirement. So I suppose the smtp server should be OK. I didn't control the smtp server, so I can't config and verify the certificate.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
