deal with google mailboxes

[Wesley Peng]

Hello,

As a mailing list server, how does postfix deal with google's mailbox 
formats?

for exmaple, all mailboxes below are indeed the same one:

usern...@gmail.com
user.n...@gmail.com
usernam...@gmail.com
usern...@googlemail.com

Can list server know them and treat them as just one?

Thanks.
