Logs from the PHP mail() function are available after logging in via FTP or SSH in the root directory under the path: .logs/mail/
Notice that the .logs directory has a dot at the beginning, so it’s a hidden directory.
For some FTP client applications, you may need to choose a view of directories and files hidden in the settings.
In the FTP client “FileZilla” , you can make the change in the menu: Server / Force display of hidden items.
