Problem with virtual_alias_maps matching for virtual_mailbox_domains only

[k***@gmail.com]

Hi, I have let's say 3 virtual domains:
- virtual.org
- example.com
- testing.net

What I want is that all mails sent to i.e. ***@virtual.org, ***@example.com, ***@testing.net go to ***@testing.net.

I want the alias to match only the virtual domains.
With this configuration the regular expression matches all domains, not only the 3 virtual ones. So let's say I send a mail to ***@humpadoo.com it is redirected to ***@testing.net.

mail.log says:
postfix/pipe[3613]: 800A922008AE: to=<***@testing.net>, orig_to=<***@humpadoo.com>, relay=dovecot, delay=0.56, delay
s=0.39/0/0/0.17, dsn=2.0.0, status=sent (delivered via dovecot service)


my postconf -n:

/etc/postfix/aliases:
/^(mailer-***@.*)$/ ***@testing.net
/^(***@.*)$/ ***@testing.net
/^(***@.*)$/ ***@testing.net
/^(***@.*)$/ ***@testing.net
/^(***@.*)$/ ***@testing.net
/^(***@.*)$/ ***@testing.net
/^(***@.*)$/ ***@testing.net
/^(***@.*)$/ ***@testing.net
/^(***@.*)$/ ***@testing.net
/^(***@.*)$/ ***@testing.net
/^(***@.*)$/ ***@testing.net
/^(***@.*)/ ***@testing.net
/^(***@.*)$/ ***@testing.net

I know that I could handle each domain separately, and/or within the mysql database but i'd like to do this simply within the aliases file.
Referring to this link http://www.seaglass.com/postfix/faq.html#vrtglal it should work, but it doesn't... can anyone help me?
