127.0.1.1 in /etc/hosts, why?

All this disties have this 127.0.1.1 IP too? Since when? Didn't try
them recently. Before Ubuntu I was a developer for two other
not so well known distries that don't use this IP.

I am using amavisd-new and let the quarantined mails go into a mysql database.
I use then MailZu for deleting or releasing them from quarantine. MailZu uses
this infamous 127.0.1.1 IP to ask amavis for releasing emails, but amavis has
a default acl to allow only 127.0.0.1. Now I have two options, I can change
the amavis acl to allow 127.0.1.1 too, or I can change the hosts and remove
the 127.0.1.1. I don't know the right way, before I know the reason for the
127.0.1.1 IP. I have asked all the other Unix admins in my company and none
of them had ever heared from this.
