thanks Busbar i looked into that article and that looks the way forward. just to clarify few things.
i will need to change my main accepted domain dbsxxx.com on First server to Internal Relay Domain.
and create send connector for this domain to use Second Server as Smart host.
not sure what exactly i need to do on second server.
will this dbsxxx.com be accepted domain or internal relay and create one connector back to First server.
how user will send email to internal users.
i think i better start testing with one of my test domain.
thanks

looks like i got it working. but am not sure if it will cause loop etc. for incorrect email IDs on given domain. as each server sending to second one if it can't find the mailbox on local server.
i added dbsxxx.com as authorative domain on both exchange servers.
created send connector for *.dbsxxx.com on both exchange servers on first its using IP of second server as smarthost.
and on second server i used IP of first server as smarthost in send connector.
tested emails across , all working.
but not getting any NDRs for incorrect email IDs.
but thanks for the advise

Hi abustraan
I will try to put up solution together for you what I did as it's been bit time now
I had it working then we moved their users to our AD later on

Thank you.
1. Make sure both DNS able to ping each others
2. Create a forest trust
3. Create a AD account for user from new company in your AD
4. Move the mailboxes for user from new company to your mail server
