The issue with sending to a specific email is as follows:

I want to change "d181996b.ess.barracudanetworks.com" to "d181996a.ess.barracudanetworks.com". How can I do this?

This has to be done with the domain-provider of cbridgecap.com - according to whois information http://www.net.cn
this is where you can set DNS-records (this has nothing to do with PMG)
