I want to implement the ability to send emails as different user. I folowed the instructions on this page: https://docs.iredmail.org/allow.certain … .user.html

Now i can send emails from user aaa@domain.tld as any other user. I want to restrict user 'aaa' to send email only by some allowed list. For example - user aaa@domain.tld can send emails as bbb@domain.tld, but not allowed to send as ccc@domain.tld. Is there any options for this?
