How to set up a SPF record

ComplexityAdvanced

SPF allows for a domain to identify the only legitimate IP addresses that can send email on behalf of the domain. This can be used as a spam prevention mechanism for your domain email.

If Shaw is hosting your zone file, it can be managed through the DNS Manager.

You can access the DNS Manager under Advanced tools by logging in to the web portal at shawhosting.ca/.

Step one

First, verify who is hosting your zone file by performing a Whois Lookup.

  1. Use a tool like MX Toolbox to do a lookup on your domain.
  2. Look for the Name Server.
    1. If the Name Server point to ns1.shawhosting.ca, then you can create your SPF record in the DNS Manager (skip to Step 2).
    2. If the Name Server point to ns5.no.cg.shawcable.net & ns6.no.cg.shawcable.net read Shaw Hostings NS & DNS settings to find out how to correct this.
    3. If the Name Server point to something else, then you will need to create the SPF record through your 3rd party DNS provider.

3rd Party Email SPF Record

Email not hosted with Shaw hosting but DNS manager will need modification. This is what a SPF record could look like for domain email that is not hosted by Shaw.

@ TXT “v=spf1 mx:mail.insertdomainhere.com ip4:64.59.128.220 -all”

  • Although Type includes SPF as an option, TXT is the proper entry option to use.
  • Quotation marks encompass the entire text, and stores text as one string in the text field. Without the quotation marks the spaces would act as string delimiters. This record says that only mail originating from 64.59.128.220 or mail.shawcable.com can be considered legitimate email.

In case of an error, you can restore your zone file back to the Shaw default by selecting Restore Default Zone File on the top right corner menu.
