A fair thing would be that every Linode should include:
- Primary or secondary DNS hosting, with a limited number of A/CNAME/MX records for one domain only.
- Backup mail server (secondary MX) for one domain only. E-mails should be kept for a few days, maybe 2-3.
Linux users are constantly playing with their servers

, and at the same time they are receiving e-mails and DNS queries, so a secondary NS/MX for at least one domain would be
very useful.
Additional domains should be charged a small fee.
Bye.
