<div class="content wysiwyg-content">
We are running Exchnage 2003 on a Windows 2003 server. &nbsp;The eventlog logs many of the following events:<br />
Source MSExchange Transport<br />
Category: SMTP Protocol<br />
Event ID: 7004<br />
<br />
This is an SMTP protocol error log for virtual server ID 1, connection #35. The remote host &quot;1998.69.x.x.&quot;, responded to the SMTP command &quot;xexch50&quot; with &quot;504 Need to authenticate first&quot;. The full commmand sent was &quot;XEXCH50 2072 2&quot;. this will probably cause the connection to fail.<br />
<br />
All of these errors contain different IP addresses. I &nbsp;have searched for a solution for quite some time and dont seem to find the answer. &nbsp;If anyone can help with this I would be so grateful!!!
