1. A system for communicating email messages using tokens, comprising:
a memory operable to store a token-email address mapping table comprising a plurality of email addresses mapped to a plurality of tokens, wherein:
each of the plurality of email addresses is associated with a different token from the plurality of tokens, and
each of the plurality of tokens uniquely identifies a different email address from the plurality of email addresses; and

a processor, operably coupled with the memory, and configured to:
receive a request to communicate an email message to a receiver, wherein the email message is associated with a sender's email address;
determine whether the sender's email address is associated with a token from the plurality of tokens;
in response to determining that the sender's email address is not associated with a token from the plurality of tokens, generate a particular token for the sender's email address, wherein the particular token uniquely identifies the sender's email address; and
communicate the email message using the particular token instead of the sender's email address, such that the sender's email address remains anonymous from the perspective of the receiver, wherein the particular token is used once such that after receipt of the email message the particular token is erased;

a second processor configured to:
access the email message;
determine whether the sender's email address is associated with the particular token by searching for the sender's email address within the token-email address mapping table; and
in response to determining that the sender's email address is associated with the particular token, determine that the email message is not associated with a phishing threat.
