SMTP proxies are specialized mail servers that, similar to other types of proxy servers, pass simple mail transfer protocol (SMTP) sessions through to other SMTP servers without using the store-and-forward approach of a mail transfer agent (MTA). When an SMTP proxy accepts a connection, it initiates another SMTP session to a destination SMTP server. Any errors or status information from the destination server will be passed back to the sending MTA through the proxy.[1]
