[Romer Ventura]

Hello,

I have this user that lost an email, even when the server is set up  
to do lazy expunge. The mail server logs show that the message was  
received, the user also read it and he did reply to it. here is the  
mail.log

But i cant find it anywhere... Is there any way of finding where it  
went...? I've done:
grep -r 'sender at senderemail' <user>/Maildir/

And it only shows the email my user sent, not the original...


any ideas of what happen as well...?

Thanks.
