You could add a regexp file to the virtual_maps list.

In main.cf:

virtual_maps = hash:/etc/postfix/virtual pcre:/etc/postfix/virtual.re



Then create a new the /etc/postfix/virtual.re file like:

.*	allmail


Note, in my experience with doing this you need to restart postfix for 
it to notice any changes to the regexp map, unlike for the hash map.
