[imail] rejected mail

[Glenn / WCNet]

Can somebody take a look at these headers and explain what is causing this bounce?  wolfrundesign.com is a virtual host on our IMail server.  In the last few days, they have switched to DSL service with another provider, but are still using us as their mail host.  Due to our SMPT security (relay for addresses with our netblocks specified), they must now use their DSL provider's (swbell.net) SMTP server, is that where the problem lies?  But from the headers, it looks like mail.ruraltel.net is where the bounce occurred.   Glenn Z.
