I will give an example of changing the requirements for password complexity in iRedAdmin, they are used to check the entered password, for example, when creating a user or simply changing a password for a user. However, I do not recommend downgrading them.

One customer once asked to set up a forwarding of all email from non-existent addresses in his domain to a specific email address, this is usually called catch-all or luser_relay in postfix.

Once, on the same mail server with iRedMail, I needed to redirect mail from the old domain to the new one, so I decided to add an alias so as not to lose contact with clients who will write to the email addresses of the old domain.
