• Ensure that mailu runs on mysql as DB for easier SQL migrations
• Create temporary tables with the correct structure for mailu (remove where filter like domain_id=4 or email like "%@mydomain.com" to dump all domains)

CREATE TABLE mailu_domain
select
    cast(now() as date) as created_at,
    null as updated_at,
    'ispconfig_import' as comment,
    domain as name,
