I understood that, but the rewrite is done by virtual_alias_maps, not
virtual_domain_maps. so putting the domain in relay domains will not
change the situation.

you can list the domains one by one in whatever class they should be.
otherwise, put them all under relay_domains and let virtual_alias_maps
do the rewrite (which is anyway necessary. virtual_alias_domains will
only tell postfix to accept mail for that domain, it won't help for
delivery).
