All Implemented Interfaces:
Behaviour
public class ProxyBehaviour extends DefaultBehaviour
Proxy client behaviour.

This behaviour is designed for a single envelope proxy connection.

It executes the SMTP exchange up to the MAIL command and then waits for individual RCPT calls before accepting the DATA command.

Unlike DefaultBehaviour, it does NOT automatically execute the data method.
