SMTP with MMDF problem can send but cannot receive mail

I am trying to setup a mail system (MMDF) for 2 SCO machines (ver &
5.0) using SMTP on TCP/IP.

The TCP/IP are working fine between 2 machines.  Their machine names are
scoben & scobaey.  They are suppose to send and receive each other mail.  
The problem is scobaey ( ver ) can receive from the scoben ( 5.0 )
but the scoben cannot receive mail from scobaey.  I had search through the
SCO Support Desk and found similar error mentioned in the articles

   "MMDF's smtpsrvr error "421 <local_name>: Your name, '<remote_name>' is
unknown to us."  and " Mail failed. I get unknown user name or unknown
host/domain in mailbox"

I had followed the solution mentioned their and still could not solve my

Thus, I had attached the setting and some testing that I had go through:

In scoben :
        file : /etc/hosts
        file : local.chn
                scoben: scoben
                scoben.fsl: scoben

                ;  Logging levels
                MMSGLOG level=FAT,size=20
                MCHANLOG level=FAT,size=20
                AUTHLOG level=FAT, size=20

It is ok to send mail from scoben to scobaey.
when scobaey send mail to scoben, I get the message of when I run command
deliver -w -csmtp open
        <-( 421 : Your name, 'scobaey' is unknown to me )
By following the solution provided from  SCO/ssl
In scobaey, I do
        1. checkaddr -w root@scoben it returns OK.
        2. telnet scoben 25 it returns "your name scobaey is unknown to me".
        3. telnet scobaey 25 it returns OK.
In scoben, I do
        1. checkaddr -w root@scobaey it return OK .
        2. telnet scobaey 25 it returns OK.
        3. telnet scoben 25 it returns "your name scobaey is unknown to me."

This is the first time for me to setup the mail system between sco os5.0 &  The
previous time I did not any problem setting up mail server between 2 sco machines.

I hope some guru could help to solve this problem.

Thx in advance.

Problem solved !
There is a solution provided from SCO ssl under the title :
"Error:"Your name, 'systemname'. is unknown to me using MMDF on 5.0"

Thanks to all that had suggested possible solution to me.


1. Mails sent ok / receive not

We have a linux mail server installed with sendmail and popper.
Inside our net everything works fine.
Mails sent to users outside are transported as well.
But when users outside sent a mail they get the following message:

----- The following addresses had transient non-fatal errors ----

----- Transcript of session follows ----
Warning: message still undelivered after 4 hours
Will keep trying until message is 1 week, 6 days old

Could anybody help?

Thanks in advance
