where is the mail

[Alan Chung]

I have setup a qmail server and everything looks fine.  DNS is setup 
correctly pointing to it.  There is one thing strange that I can't get mail 
from Mailbox.  But whenever I restart qmail daemon, those test mails that I 
have sent all come in once.  I can't find where they are.

Does anyone have a similar experience?

Thanks in advance.
