We're experiencing difficulties with adding mailboxes or domains to the blacklist, encountering two specific problems.
In the first scenario, after adding a mailbox or domain to the blacklist, we attempt to send an email from that address to a domain configured in the Mail Gateway, only to find that the email is accepted, which shouldn't happen.
In the second scenario, after we add a mailbox or domain, refreshing the interface results in the mailbox or domain being removed from the blacklist entirely.
