Abstract

Official abstract text for this publication.

A system is provided for enabling a source MTA to communicate with a target MTA via an SMTP proxy using SMTP commands for transmitting email messages in a networked environment. An email message may be received by a source mail transport agent (MTA) and the source MTA may route the incoming email message to a target MTA via an SMTP proxy. The SMTP proxy may serve as an intermediary proxy server for enabling the source MTA to communicate with an external and internal target MTA. The SMTP proxy may connect to a target MTA via a connection command, and the SMTP proxy may implement custom SMTP commands to communicate additional information about the source MTA to the target MTA. The system may additionally enable the SMTP proxy to perform actions designated by the SMTP commands and to communicate the result of the SMTP proxy's actions back to the source MTA.

First claim
