Jack,
My server is a linux box running sendmail, procmail, and dovecot, I  
use ldap on the backend.  Most of my clients use Horde for webmail,  
but I have some that use outlook.  The emails are missing, missing.   
Neither on client or server.  Thing is I looked on my backups (7 days  
worth) and supposedly missing emails werent there either.  So its hard  
to tell how long they have been missing.  Also, this server was put  
online 2 years ago, so all mailboxes were migrated from the oldserver  
to the new one and renamed oldmail.  Nothing in their either.  Were  
there any gotcha's on the upgrade?  Im not one to upgrade unless there  
are security issues or problems and my mailserver has been extremely  
stable
