I migrated all domains but one to a new server, and disabled all domains but the one left on the old server. Now when I try to create a new alias or user with the global admin on the one domain left on the old server, there are no domains in the drop-down, and when trying to create a user I get "No domain under control." When I try to create an alias I'm redirected to a plain white page with nothing on it but the text, "(False, 'PERMISSION_DENIED')".

I am planning to move this domain to a separate, new iRedMail server, but in the meantime I need to create one alias because of a situation related to the migration. Is there a quick and easy way to do this, like by bypassing iRedAdmin-Pro and doing it directly in Postfix for example? If it's too big a problem, to deal with an ancient installation I can live without it, but I thought I'd ask.
