SYMPTOMS
The Post Office Protocol version 3 (POP3) service for Microsoft Commercial Internet System may generate many event ID 47 warning messages in the System event log that contain the text &quot;AUTH twinkie failed for client at host x.x.x.x,&quot; where x.x.x.x is an Internet Protocol (IP) address.



CAUSE
This problem may occurs if an older mail clients deliberately sends a false &quot;twinkie&quot; authentication request to determine what features the mail server supports. You can safely ignore these messages. However, these messages may create a large number of messages in the System event log on a busy site.
