Ahha,
Finally I found someone is trying to do the same thing and is having
the same problem. I just solved my own two days ago. And I am glad to
share with you all.
First this is really mail configuration problem. Look
at/usr/spool/mail/postmaster all the missing mail is there.
Second, I couldn't find any documentation in the Linux documentation
project. However, I found the answer in my slackware 3.0 distribution.
Specifically, /usr/doc/sendmail/faq if the documentation is installed.
The problem is coused by that the mail daemon does not recoganize
that itself live in your linux box as whatever.whatever and decide to
return it.
There are probably several ways to fix it. The linux box owner need
to edit the /etc/sendmail.cf add a line
Dcw mtepel.student.harvard.edu
under
Dcw localhost
Hope you got the idea.
