CentOS 4.8, sendmail 8.13 Hi All: I have a couple of questions regarding the routing of outgoing emails. I have spent several hours doing Google searches but I have not come close to what I am looking for. If someone can give me push in the right direction I would greatly appreciate it. We currently have three domain names (two for our development company and one for our production company). We have one mail server in our development office that hosts all three domain names. Actually we just treat the three domain names as aliases of the mail server (via the local-host-names file and I do not see a need to change this. What I would like to do is route (relay?) any outgoing emails that are from emails addresses using only one of those domains to a separate SMPT server. 1. Is this possible? 2. What is it called? 3. Can you provide examples or links to relevant docs? TIA Regards, Hugh -- Hugh E Cruickshank, Forward Software, www.forward-software.com
