Technically, everything in the local part of the address (the bit before
the @ sign) is supposed to be interpreted *only* by the host given in the
domain (the bit after the @ sign). So if Gmail wants to interpret
"foo.bar at gmail.com" and "foobar at gmail.com" the same, they can.
Or for that matter, "raboof at gmail.com". Although that would be silly.
Postfix, I think, interpets "foo+bar" the same as "foo".
