create table alias_domain (alias ..., target ....) ....
insert into mailbox values ('wjames', 'dxx.go.ug');
insert into alias_domain values ('dxx.co.ug', 'dxx.go.ug');
virtual_alias_maps = ..... mysql:/etc/postfix/per-domain-alias.cf ...
in the latter,
query = select concat(user, '@', domain) from alias_domain, mailbox
where %d = alias and domain = target
The idea is to only return a result if the "target" address exists
(otherwise, you break recipient validation).
then check with 'postmap -q':
# postmap -q wjames@... mysql:/etc/postfix/mailbox.cf
# postmap -q wjames@... mysql:/etc/postfix/per-domain-alias.cf
