My guess is that on the old server, domain.tld was in Postfix's
mydestination so that address at domain.tld was a local address and only
referred to alias_maps and not virtual_alias_maps, whereas on the new
server domain.tld is a virtual_mailbox_domain, thus postfix is looking
in virtual_mailbox_maps for address at domain.tld and not finding it..
