refused 'mail from' because return MX does not exist

I am getting this error only for emails sent from my Exch 2K server to users of a mail server in China:

There was a SMTP communication problem with the recipient's email server.  Please contact your system administrator.
            <INA-MAIL-01.inasoft.com #5.5.0 smtp;554 refused 'mail from' because return MX does not exist (#5.5.4)>

Here is the header of a failed email:

Microsoft Mail Internet Headers Version 2.0

Here is our setup. We have a Linux server, linuxbug, that runs a bug tracking program called Bugzilla. Bugzilla sends emails (relays) to a distribution list (sr@inasoft.com) on our exchange server. Only recipients that have addresses ending in @njinsoft.com (our China site) get the error & the email is not delivered. If I send an email directly from the exchange server to a @njinasoft.com address it works fine. To work around this problem I have set up a rule in outlook to forward messages from sr@inasoft.com to the @njinasoft.com people.

I am guessing my problem lies in one or both of the lines below from my email header:

Received: from linuxbug.inasoft.com (localhost.localdomain [127.0.0.1])
Received: (from bugzilla@localhost)

I am also guessing that I will need to modify bugzilla or sendmail on my linux server to fix this. I am pretty new to linux so I want to make sure I am going down the right path....

Taking a look at your error I did an nslookup:
%nslookup -type=mx
Default Server:  localhost.droopy.com
Address:  127.0.0.1

> njinsoft.com
Server:  localhost.droopy.com
Address:  127.0.0.1

*** localhost.droopy.com can't find njinsoft.com: Non-existent host/domain
> inasoft.com    
Server:  localhost.droopy.com
Address:  127.0.0.1

Non-authoritative answer:
inasoft.com     preference = 10, mail exchanger = inamail01.inasoft.com

Authoritative answers can be found from:
inasoft.com     nameserver = ns1.nextlevelinternet.com
inasoft.com     nameserver = ns2.nextlevelinternet.com
inasoft.com     nameserver = dns1
inasoft.com     nameserver = dns1.inasoft.com
inamail01.inasoft.com   internet address = 66.185.168.46
> njinsoft.com
Server:  localhost.droopy.com
Address:  127.0.0.1

-------------------------------
I would make your external DNS records for MX match the working site (or where ever you would like it to route)
Wait a while, and try them again (the dest. maybe cached)

Actually that nslookup should be for njinasoft.com not njinsoft.com

You can edit the genericstable on your  sendmail box and have it map that outbound user to a different domainname.
what version of linux is it?

I am pretty new to Linux, any instructions on how to edit the genericstable would be most appreciated.

I found that WebAdmin allowed me to add a masquarading domain to Sendmail but I still get the original error. Do I need to stop and restart the sendmail service?

you should have a file called /etc/mail/genericstable  if this file is not present do the following to find it
grep genericstable /etc/mail/sendmail.cf
neil@hope:/etc> grep genericstable sendmail.cf

it will look something like this:
Kgenerics hash -o /etc/mail/genericstable.db


edit this file ( /etc/mail/genericstable)  notice no .db on the end

add:
bugzilla-daemon<TAB>bugzilla-daemon@njinasoft.com

***The <TAB> is the tab key***
from the unix prompt (as root) put
makemap hash /etc/mail/genericstable </etc/mail/genericstable

now any mail leaving this system matching bugzilla-daemon will be bugzilla-daemon@njinasoft.com
and everyone else will be as they were before.

Unfortunately I am unable to work this issue any further. The company I work for ceased operations last week & I am out of a job.

I think h5uj was on the right track so I am going to give him/her the win. I wish I could actually try his suggestion..
