I use SquirreMail 1.4.3a-9.EL4 as mail client.  It's web based.  I did not
do anything special.  As the first I do every morning, I just went through
various folders and deleted those messages I did not want to keep after I
read.  I have root access to the mail server.  Under my mail directory, I
don't see any additional folder created to store those lost messages due
to INBOX over quota.  We don't have quota on INBOX here.

The thing confused me is if it was me who deleted all the messages in
INBOX, say by accident, those messages should be saved in the TRASH
folders.  However, the TRASH folder just had old trash and the newly
deleted messages that I was aware of.  In another word, those lost INBOX
emails are not found in the TRASH folder.

Any other thoughts, anybody?
