Hello there, and thanks so much for your help
I've got a web+mail server in the same machine. PHP's mail function is
disabled, but other 3rd party functions such as PHPMailer can use
sendmail to potentially send emails, as if I was invoking it from a shell
echo hello | sendmail m...@email.com
Unlike submission with SMTP, Postfix has no destination access
controls for email that is submitted with the Postfix sendmail
command.
However, you can disable Postfix sendmail submission from web
applications. There is a documented example:

Thanks Wietse. authorized_submit_users along with a script to generate a
file did the trick.
Cheers,
Ignacio
