You could setup the send connector on the second server and use the first server as the smart host?

Do you have any SPF record configured for your domain which may be set to only allow a specific source to send your email?

From local Exchanges there is no any SPF record. but the first exchange sending through Smart Host
OK. I have no clue.

Hope one of the other Experts can help out here as Im interested to know the answer.

Thanks

I would recommend to use http://www.dnsstuff.com/ for testing your external DNS (SPF Record etc.).

It could also be that your email-domain is listed in a blacklist how is used be the receiving email system.
Therefor you can also use http://www.dnsstuff.com/.
