Hi
If you mean to actual check that the email is in fact a real email. Not
syntax wise but that an actual server has this actual email for an user then
the short answer is. You cannot.
Some email servers will report back "unknown user" some will just ignore you.
So will report back that mail could not be delivered. some will not.

So what we normally do is to use verification.
You enter email.
System sends you activation mail
You click it.
Email accepted.

@Pradeep-Kumar

In LineEdit itself and checking if the email is correct or not whenever user clicks on submit button.

Hi It depends on what server you are planning to use to send the emails.
Say you use a google account you can use SMTP and maybe

There are a number of sites providing this service, most of them commercially.
http://verify-email.org/ has a free API limited to 5 checks an hour. https://emailhunter.co/ limits to 150 a month
