Sometimes automated services or people need to contact some domain administrator for a certain domain. There are a couple of addresses that should be present by default. Google uses these addresses to notify you when they put you on their malware blocklist:

  1. abuse@
  2. admin@
  3. administrator@
  4. contact@
  5. info@
  6. postmaster@
  7. support@
  8. webmaster@

I think I need these for my domains to be present by default:

  1. abuse@
  2. postmaster@
  3. hostmaster@
  4. webmaster@
  5. root@
