Hi folks,

    I am stuck in sendmail. I have a wee network as below
at home.

       A                                       B
    --------             --------           ---------
    |Linux |------------| HUB   |---------- | Linux |
    --------            ---------           ---------
                            |
                            |
                            |
                         -------   
                         |Win95 |
                         --------

   Both A and B have same network addresses. Both are
running sendmail. But, B can't send mails to A, nor
A to B for some unknown reason.

  A is 192.168.32.6
  B is 192.168.32.7

The only thing I can think about is their names.

  A is sean.ai.is.uec.ac.jp
  B is bryce.lit.tamagawa.ac.jp

I wrote, however, IP - hostnames.domainnames in /etc/hosts.
I also initialized /etc/aliases. But the more I send mails
from either machine, the more the machine eats them up and
keeps them in spools and would not send them. Do I have to fiddle
with sendmail.cf or should I do something else such as making
the domain names same?
I seem to have had no such trouble before but only after
I upgraded the kernel, I was stuck. (A) machine is mobile,
so I set /etc/network 127.0.0.1, but wrote /etc/pcmcia/
network.orts as usual. No DNS,Gateway, but just /etc/hosts.

Anyone give me solution please.

Thanks in advance.
