GroupWise 7 user continually having troubles sending email to two different users on msn.com. The client Sent Items Properties is "Transfer Delayed". In the GWIA log I'm seeing a lot of Command: msn.com Response: 450 Host down (msn.com) entries.
He receives messages from these users, and receives messages where he and the msn.com users are in the receipient list of another user on another email system.
My question is what is causing the problem with msn.com? Please help, thank you.
