1,Open the mail test page: https://www.mail-tester.com/but they already registered with that email..but get no confirmation on their email so they can confirm their email and log in
2.Copy the email address they provide.
3.Register an new account on your forum using that email address.
4.Go back mail-tester.com and see the results.
There is many reasons email will not reach a users inbox. That service will not reject email for any reason and will analyze it for reasons it may not get delivered. If it finds any issues related with reverse DNS, SPF, DKIM or DMARC you should address them because anyone of them can cause email to not reach a users inbox. These things are all configured through your server/DNS and have nothing to do with phpBB.
If no email is received by that service then it's a problem server side.
