IMPROVING ATTACHMENT HANDLING DURING EMAIL DELIVERY

摘要

A system and method for improving attachment handling during email delivery is disclosed. A partial message data structure stores all data associated with an email except the email's attachments' contents, although attachment contents may be stored in the partial message data structure if necessary (400, 402). When an email is sent to a recipient, a message router constructs the full email message including attachments from the partial message data structure and the stored attachment contents before sending the email to an SMTP server (404, 406). When an email is received from an SMTP server (600), a message router transmits the email to a message parser that parses any attachments from the email and stores the attachments in persistent storage (602). The message parser then sends a partial message data structure containing data associated with the email and references to the email's associated attachments to the message router (604). The message router transmits the partial message data structure to a server for delivery (606).
