Sorry, I should have thought of that earlier! I've attached the latest bounce message below.
This bounced email (and the one just after 3:00 p.m. today) were sent from my Mac using Eudora. The one that bounced this morning was sent directly from my Sonic shell account using UNIX Mail. So the only commonality was the Sonic outgoing mail server.
