Slow Mail Performance and Notification of Delay When You Send Mail to Another Domain

This article was previously published under Q294175
When you send mail to an address in another domain, the mail may not be delivered and you may receive a delay notification stating that the server is still trying to send the mail. The system may also experience slow mail performance.
This occurs when your mail goes through a Simple Mail Transfer Protocol (SMTP) server that is configured to use an external Domain Name Service (DNS) server to resolve names.
This behavior occurs because of the way mail to a nonexistent (for example, misspelled) domain is processed on an SMTP virtual server that uses DNS to resolve names. Instead of sending an non-delivery report back to the sender, the server places the mail in a retry queue until the message expires.
