This article was previously published under Q286673 SYMPTOMS When you use the Microsoft Internet Information Services (IIS) 5.0 Simple Mail Transfer Protocol (SMTP) service to relay messages to Microsoft Exchange Server 5.5 or other SMTP mailers, you may find that some messages take a long time to deliver and some messages are not delivered at all. Additionally, the
following event is logged in the Event Viewer: Type:
Warning Source: Smtpsvc Event ID: 4000 Description: Message
delivery to the remote domain DomainName failed. The
connection was dropped by the remote host. CAUSEThis behavior occurs because the Exchange Server 5.5
