not working on my hostinger server

hello bro , i'm using your script on my server hostinger i get this error


220-cpl17.main-hosting.eu ESMTP Exim 4.96 #2 Thu, 08 Jun 2023 12:53:02 +0000
Connection success gmail-smtp-in.l.google.com
HELO maxtvs.net
220-We do not authorize the use of this system to transport unsolicited,
MAIL FROM:<[email protected]>

RCPT TO:<[email protected]>
250 cpl17.main-hosting.eu Hello maxtvs.net [109.106.251.101]
RSET
QUIT
email <[email protected]> exist!


can you please explain what should be changed in class.verifyEmail.php

hi!

1. in "MAIL FROM" use real email
2. make sure DNS records for "maxtvs.net" is valid
"A" record
"MX" record
"PTR" record
"SPF" record
The server running the script should be allowed to send emails on behalf of the domain "maxtvs.net"


The recipient server thinks that you are a spammer, see the answer:
220-We do not authorize the use of this system to transport unsolicited
