SYMPTOMS
You may experience the following symptoms in a Microsoft Exchange Server 2003 organization or in a Microsoft Exchange 2000 Server organization::
 * When you send e-mail messages to certain domains, the e-mail messages are retried until they expire.
 * The recipients of the e-mail messages may receive multiple copies of an e-mail message when the e-mail messages are retried.

<div class="cause_section">

CAUSE
This problem may occur if the target server generates a multiline response to the DATA command that is issued by the Microsoft Exchange server. The Simple Mail Transfer Protocol (SMTP) service on the Microsoft Windows Server 2003 server on which Microsoft Exchange is installed does not handle multiline responses. This problem is more likely to occur when there is a delay introduced between the first line and the last line of the multiline response that is made to the DATA command.

The following is a sample of a multiline response:

354-Line 1

354 Send message

Note The &quot;-&quot; symbol is used instead of a space in multiline messages.
