RFC 2821 pacing non-conformance


We were invited to subscribe to a mailing list, on a host running the Lyris mailing list manager. Unfortunately, Lyris is too impatient to wait the RFC 2821 sugggested 300 seconds between conversation elements. We mark the conversation, and the timestamps, showing its impatience. Additionally, that software changed the userid to a leading CAPITAL "H"; how rude. Ahhh well.
