First thanks in advance for any advice on the challenge I'm trying to resolve.
We have a domino servers with various domain names we are servicing our different group of companies.
We have a situation where we would like our users from lets say company3.com route to a different gateway than company1.com and company2.com (different new internet circuit with seperate IP address) so that information on header emails could not be traced back to company1.com and company2.com.
From external configuration, company3.com would make changes to point it's MX record and ptr record to new external IP address.
Challenge is to find solution to route outgoing emails from company3.com to seperate gateway.
Note: We have two Barracuda Firewall Spam Filter. One servicing company1.com and company2.com. The second one is for new circuit servicing company3.com.
