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:
“This is really the common mentality of prisoners: they read with great attention all the articles that deal with illnesses and send away for treatises and “be your own doctor” or “emergency treatments” and end up by discovering that they have at least 300 or 400 illnesses, whose symptoms they are experiencing.”
—Antonio Gramsci (1891–1937)
