Zimbra installed. Yahoo configured. Yahoo synch started. After a few hours MS Security Essentials (MSSE) warns about a keylogger payload in a specific msg. MSSE throws the message away. and Zimbra tries to sync the same message again. How can I find out WHICH message in Yahoo is infected? I only have the Zimbra msg number "xxxxx xxx.msg", not the related Yahoo mail info....

I want to throw the affected msg away from the source (yahoo) to break this infinite loop.
