Debug log only shows the addresses of the sent emails:

Headers: , To: ***@****.es, Subject: [*****] New user account
Headers: , To: ****@****.net, Subject: Bienvenido a ****!

The debug on the test email shows this:

CLIENT -> SERVER: EHLO thewebsite.com
CLIENT -> SERVER: AUTH LOGIN
CLIENT -> SERVER: [credentials hidden]CLIENT -> SERVER: [credentials hidden]CLIENT -> SERVER: MAIL FROM:<[email protected]>
CLIENT -> SERVER: RCPT TO:<******@gmail.com>
CLIENT -> SERVER: DATA
CLIENT -> SERVER: Date: Wed, 10 Mar 2021 10:10:33 +0000
CLIENT -> SERVER: To: *****@gmail.com
CLIENT -> SERVER: From: thewebsite<[email protected]>
CLIENT -> SERVER: Reply-To: thewebsite<[email protected]>
CLIENT -> SERVER: Subject: prueba
CLIENT -> SERVER: Message-ID: <[email protected]>
CLIENT -> SERVER: X-Mailer: PHPMailer 6.2.0 (https://github.com/PHPMailer/PHPMailer)
CLIENT -> SERVER: MIME-Version: 1.0
CLIENT -> SERVER: Content-Type: text/plain; charset=UTF-8
CLIENT -> SERVER: 
CLIENT -> SERVER: prueba
CLIENT -> SERVER: 
CLIENT -> SERVER: .
CLIENT -> SERVER: QUIT

It doesn’t show anything about the server. The EHLO is the domain of the website, but we use hostnames of the servers to connect to them.

The server is fine, ping and traceroute points to the right server, I can configure the servers on other clients like thunderbird or outlook, even the webmail, but the only part that doesn’t works is WordPress with EasySMTP installed. I don’t know what happens. I also talk with the support of cPanel and them confirms me that server2 is resolving fine to server1.

Thank you so much.
