It's been a while, and what with DKIM & DMARC and all, I've lost track of the details. So I wonder if someone might offer some quick advice on configuring one server as the outgoing server for multiple domains, all behind a single IP.
Create one SPF record for this server and let all domains point to it. For DKIM, you can set up opendkim-milter with multiple domains.
Then set up virtuser-aliases for every domain if needed. Set up relaying for the existing addresses only if possible to avoid backscatter.
