create aliases with the same name for different local domains

Hi, all

I have a qmail-ldap with several sub-domains, eg:
 [email protected] [email protected], [email protected]

domain1, domain2, and domain2 are in control/locals, and email users
of these domains are stored in LDAP.

I use /var/qmail/alias/.qmail-???  to create groups (distribution
lists) for these domains, but I need to create groups with equal names
to receive email lists for users of these domains, eg:

[email protected]
[email protected]
[email protected]

If you create the /var/qmail/alias/.qmail-it only, it will not know
how to distinguish the domain (it will only deliver to the
defaultdomain).

So I tried to create /var/qmal/alias/ these files:

   .qmail-domain1-support
   .qmail-domain2-support
   .qmail-domain3-support

... with theirs respective users..

On virtualdomains, I put:

[email protected]: alias-domain1
[email protected]: alias-domain2
[email protected]: alias-domain3
or
[email protected]: alias-domain1-support
[email protected]: alias-domain2-support
[email protected]: alias-domain3-support

However, it is not working (Sorry, _no_mailbox_here_by_that_name is giving)

So I removed domains 1, 2 and 3 from the control/locals and from then
Qmail is reading the "alias" files. But it still did not work!

What is the most correct way to make these aliases work by keeping the
domains in the control/locals (since all users are local), but also
being able to create the groups in the alias, as the same name but for
different domains?

What am I doing wrong?
