  • SPF
  • Where the SPF record is not already defined by the client, we use: "v=spf1 a mx include:spf.host100.net.nz -all"
  • We include spf.host100.net.nz to permit our outbound antispam systems.
  • DKIM
  • We use DKIM by default.
  • To properly implement DKIM for services not managed by us, we would need selector(s) and public key(s) for any node(s) sending email as [domain].
  • Our systems currently require using a selector called "default".
  • We're happy to provide selector(s) and public key(s) for the web / email service(s) you have with us, to allow you to configure this yourself.
  • DMARC
  • Where the DMARC record is not already defined by the client, we delegate this to a policy domain, and use: "v=DMARC1; p=quarantine; sp=none; fo=s; rf=afrf; ri=86400; adkim=r; aspf=r; pct=100;"
  • SSL / TLS
  • We use Server Name Indication (SNI) and require TLS 1.2.
  • DNS
  • Please ensure that you review the DNS records for [domain] regularly.
  • SPF records need to include every server that sends email from [domain].
  • DKIM records need to include the public key for each and every selector that is used by any server that sends mail as [domain].
  • Please email changes and queries to postmaster@host100.net.nz.
  • Grey Listing
  • After a number of incorrect authentication attempts the source IP address will be Grey Listed. To temporarily White List the IP address to correct and reauthenticate the email credentials, try browsing to the website ([domain]) or webmail page ([domain]) and complete the CAPTCHA verification.
  • Technical Assistance
  • Please forward all information you have to postmaster@host100.net.nz, and contact us to notify of this.
  • If relevant, please include saved copies of emails (including headers), as well as any logging/reporting information you have.
