When i put below code, it works fine perfectly
What this below code mean?

$mail->SMTPOptions = array(
'ssl' => array(
'verify_peer' => false,
'verify_peer_name' => false,
'allow_self_signed' => true
)
);

It means that the TLS certificate provided by your mail server does not match the host name you asked for. In your code you're asking to connect to smtp.mydomain.in, but the server says it's called outbound.mailhostbox.com, and a certificate for one will not match the other. Check that you're using the correct host name. It can also happen if your ISP redirects outbound SMTP traffic to their own server - something which you would not be able to detect without certificate verification.

Setting those options will make it "work", but it does so by turning off verification of the certificate, which may mean that you are vulnerable to man-in-the-middle attacks, and so is unsafe. Figure out exactly why you need to do that.

All of this is covered in the troubleshooting guide.

Thank you so much .... @Synchro

@edukondalu123 Thanks, the code worked for me

[Synchro]

@klever34 Really, don't use that code: fix it properly like the guide says. It's like saying that leaving the front door of your house open is a "working" solution to having to remember where your keys are; there are implications to doing that.
