This applies to my VPS that runs both the web server (nginx) and email server (dovecot + postfix) for several domains.
Hypothetically, suppose that I have domain company.com, and that I additionally purchased the .org, .net, .us and .uk variants of the same domain to deter any unfortunate incidents. The additional domains (every TLD not .com) will serve only to redirect to company.com.
Question: how do the DNS records for the primary domain and all the redirect domains differ?
- What DNS records do I need, at the bare minimum, for the redirect domains?
- For email subdomains such as
smtp, do the redirect domains require the same?
- What should MX records look like? Is it just
1 mail.company.tld.across the board?
- Am I correct in assuming that need an
SSLcert for every domain, even the redirecting ones?
Thank you in advance!
