@boomerang,
I live in one side of a duplex type "town house". There is, in this neighborhood, a system where every x number of feet along the street there is a multi box contraption set on a pole: probably 2o boxes, plus two large boxes with keys to open them put in your box if you have had a package delivered.
Egads, I hate this kind of mail delivery.
My last two houses, covering a span of 35 years, were old craftsman homes. The first had no mailbox but I set one on the porch - I think that was a P.O. no no, but it didn't matter - mail was delivered there, and I got to be friends with the two mail deliverers over the years. The second craftsman had a glassed in front porch with a drop slot, a system I really liked. Also got to be pals with that delivery guy. With both of these situations, there was plenty of room for all kinds of mail. With the present multibox system, the boxes are nearly silly in their smallness.
I cringe, as I used to specify those kind of systems for housing tracts, back when I was designing for a housing development client.
