one's own messages appearing

[Bill Troop <billtroop@xxxxxxxxx>]

Carl, when I send a message to the list from my basic computer using 
Eudora, the message never comes through as a message from the XyWrite 
list, hence it never gets into my XyWrite mailbox. But if I send a 
message from the Gmail page of a browser, on another system, then it 
does get sent over to me as part of the list's messages. Can you tell 
me what is going on and how to fix it? Many thanks,
