Hello Arai-san,

Here is how I do it.  In /etc/sendmail find the section that says "local
info".  At the beginning of this section, you should see a line that says:

  Cwlocalhost

After that line, enter the following line:

  Fw-o /etc/sendmail.cw

This tells send mail to look in the /etc/sendmail.cw file for a lists of
hostnames that it is allowed to accept mail for.  Here is how my section
looks in my /etc/sendmail.cf file:


  ##################
  #   local info   #
  ##################

  Cwlocalhost
  # File containing the names of hosts for which we receive mail.
  Fw-o /etc/sendmail.cw

Now, create a file /etc/sendmail.cw  In this file, you list the fully
qualified domain names of all the hosts that you will accpet mail for, one
on each line.  In your case, the /etc/sendmail.cw file should look like
this:

  explosion.t.u-tokyo.ac.jp
  explosion.chem.t.u-tokyo.ac.jp

Sendmail should then accept e-mail for both domains.  Of course, you have
to kill and restart sendmail after you make these changes to the config
files.
