I need to configure a sendmail server as a relay host that will only deliver/relay emails addressed to my domains. After messing around with access, mailertable, etc. nothing works. What I need is the following:
Email sent from another host running a web app to sendmail relay agent.
If email is NOT addressed to *@domain1.com, *@domain2.com, *@domain3.com email is rejected.
If email IS addressed to *@domain1.com, *@domain2.com, *@domain3.com email is relayed to our smarthost mail.domain1.com
I hope that explains it enough.
