[SOLVED] users aren't getting email confirmation

Fresh install of Joomla 4.

set Allow User Registration => (Yes, independent of CMS, "Allow Registration")
set Email Confirmation => (Yes)

and I set the joomla registration plugin "User_Joomla!" => Notification Mail to User => (No) just like I saw you in the video

My email server works because I am able to send email out to different yahoo accounts, and the account I'm testing on has a yahoo email account, so emails are getting there, but when I try to register to my website using the yahoo user account, the account never receives any confirmation email with a link inside. I have check the spam folder consistently and there is nothing there. I even deleted all spam email and ran a test and still nothing.I keep deleting the user on the backend and keep testing but nothing changes.

Turning on joomla "system debug" and setting it to debug "everything" shows absolutely nothing in any of the files. I clear all debug files and tested and nothing gets logged when I try to register to the website.

Within CB > User Management click the checkbox next to the user you want to email. Next click Mass Mail and try sending them an email. This will let us know if emails are working in general or if it's just the confirmation email not being sent.

Please close ticket. I found that I needed to have an extra MX record in my DNS records mail.domainname.com. This had nothing to do with your community builder. Now all users on yahoo and google mail are getting confirmation emails with registration links.

Sorry!
