Common Local-part Semantics
According to RFC 5321 2.3.11 Mailbox and Address, "...the local-part MUST be interpreted and assigned semantics only by the host specified in the domain part of the address.". This means that no assumptions can be made about the meaning of the local-part of another mail server. It is entirely up to the configuration of the mail server.

Famous quotes containing the word common:
“Why does not the kitten betray some of the attributes common to the adult puss? A puppy is but a dog, plus high spirits, and minus common sense. We never hear our friends say they love puppies, but cannot bear dogs. A kitten is a thing apart; and many people who lack the discriminating enthusiasm for cats, who regard these beautiful beasts with aversion and mistrust, are won over easily, and cajoled out of their prejudices, by the deceitful wiles of kittenhood.”
—Agnes Repplier (1858–1950)
