Definitions for "Mail box"
an area that stores your unread and read email messages
I saw today (2001-04-28) at the store a Visual Mailbox made of glass. It was clearly mold blown, whether by hand or machine, I don't know. I should have gone and gotten my camera. The top slot was protected with an aluminum cap hinged on a heavy wire around the neck and the surface was ground. The bottom was more aluminum with a catch latch to keep the mail from falling out the bottom. The young lady said it had been on her grandmother's front porch until she died in 1970 ("It's really old", this very young lady said.) When I did a web search this site has a three part tin top with a glass bag (half round) under it. Mail goes in a slot and the top opens to get mail. $35. A box almost identical to the one shown me, the bottom clip being smaller is shown at this site to support a finished eBay auction. $75.
A storage place for emails. When a message is sent to your email address, it stays in your mail box until you read it. Once you read it, you can delete the message or save it to your computer's hard drive.
