Domains rationalisation

The aim of this project is to reduce the number of domains I use.

• copy all records from alt.tf to ois.tf (easier this way because alt.tf is almost empty)
• delete alt.tf zone
• rename ois.tf zone to alt.tf
• serve ois.tf and alt.tf with the same zone file
• clean all remaining traces (emails, configurations, certificates, etc.)
• announce changes to users
• stop serving ois.tf zone altogether
• wait for domain expiration

• copy all records from oxynux.org to alt.tf
• redirect all @oxynux.org email aliases to coresponding alt.tf addresses
• redirect all HTTP request to oxynux.org (and subdomains) to corresponding alt.tf domain or subdomain
• update all accounts across the web using an @oxynux.org address (no worries)
• create an email responder for all @oxynux.org addresses
• renew domain once
• wait for domain expiration
