Strange mail error message from this list

I sent one email to this list yestoday and got a mail error notice in my mailbox today. Seems that I sent the email to an expired address and the got rejected. but I only sent the email to this list NOT to this address:! Is this normal? as I understand, I sent msg to this list and the server will forward my msg to everyone. that means, any msg sent to this server will be forwarded to this unvalid address and a error notice will be sent back. Is it? The notice i got is: \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ The original message was received at 2005-05-05 12:23:02 +0100 from postoffice.armilan [10.0.0.1] ----- The following addresses had permanent fatal errors ----- -----Transcript of session follows ----- ... while talking to postoffice.armilan.:
