Awww, come on... don't leave 'em hanging.  You should at least summarize..
% has lower precedence than @, but is evaluated left to right like @.
It's precedence is equal to !.

the following are "similar" addresses:

    user%addr1@addr2
    addr1!user@addr2
    addr2!addr1!user

In all cases, the mail goes thru addr2 first, then to addr1, then to the user.
